What Is Blood Blazon?
Cherry-red blood cells (chosen erythrocytes) have a blazon of antigen on their surface. Composed of carbohydrate molecules, these antigens are chosen agglutinogens. There are two types of agglutinogens: blazon A and type B. The blazon of antigen on the surface of your blood-red claret cells determines your blood type.
There are four bones blood types, made up from combinations of the type A and type B antigens.
Type A: The cherry blood cells accept the type A agglutinogen.
Type B: The crimson blood cells accept the type B agglutinogen.
Type AB: The cherry-red blood cells have both blazon A and type B agglutinogens.
Type O: The red blood cells do non have any agglutinogens at all.
There is some other poly peptide (called Rh factor) that is sometimes found on ruby blood cells. If a person has Rh factor, their blood blazon is called "Rh positive." An individual lacking this poly peptide is called "Rh negative." Combined with the ABO blood types described above, a person may exist A+, A-, B+, B-, AB+, AB-, O+, or O-.
Blood Types Around the Globe
Claret Group Poll
Blood Types Around the World
Blood types vary depending on the geographical region: Scandinavians take a loftier probability of carrying the A blood type, while those ethnic to key Asia are more likely to conduct the B blood blazon. The O blood type is the most common claret blazon around the world.
According to the National Center for Biotechnology Information (a molecular biological science resources funded past the government), the breakdown of claret blazon by region is:
Blood Blazon A: Cardinal and Eastern Europe
The A blood group is common in primal Europe. Nearly half the population in Denmark, Norway, Republic of austria, and the Ukraine have this blood type. This blood type is likewise found in high levels amongst minor, unrelated groups of people. In Montana, 80% of the Blackfoot tribe has the A blood group.
Claret Type B: Asia
The B blood type is rare in Europe (well-nigh 10% of the population), but fairly common in Asia. Nearly 25% of the Chinese population demonstrates this blood type. This blood type is also fairly common in Bharat and other Central Asian countries.

Blood Blazon AB: Asia
The AB blood blazon is the rarest of all. It is found in upwardly to ten% of the population in Nippon, Korea, and Mainland china, only is extremely rare in other regions.
Blood Type O: The Americas
The O blood blazon is the most common effectually the globe, and is carried past nearly 100% of those living in S America. It is the virtually common blood type among Australian Aborigines, Celts, those living in Western Europe, and in the United States.
Rh Cistron
The majority of people in whatsoever geographical region are Rh positive. Caucasians are the most likely to be Rh negative, with approximately 17% of blood donors demonstrating a lack of this poly peptide. Native Americans are the next highest proportion of the population to test as Rh negative: approximately 10% of donors from this population lack this protein.
Coconut Juice Blood Transfusions in Globe War II
Every bit World State of war 2 raged through the Pacific, blood products were in curt supply. In emergency situations, Japanese and British medics would resort to coconut h2o. Coconut water (the juice within a immature kokosnoot, non "milk" which is made from grinding upwardly the meat of the fruit) has fewer electrolytes than blood plasma, just information technology is sterile and works in a similar fashion to a saline Four drip. In a compression, coconut water is tolerated fairly well by humans. In fact, kokosnoot water preserves teeth better than milk - something to go on in mind the next time a tooth gets accidentally knocked out!
The History of Blood Transfusions
In the 19thursday century, no one understood that people had different blood types. Claret transfusions often resulted in death, equally the receivers immune arrangement would attack the strange, unmatched blood that was transfused.
The history of blood transfusion goes all the manner dorsum to the 1600's, when William Harvey discovered the circulatory arrangement. By 1658, Jan Swammerdam was viewing red blood cells through a microscope. The very offset transfusions occurred in dogs, as the English language physician Richard Lower demonstrated that a dog could be kept alive by transfusing blood from other dogs.
Unfortunately, the move to human transfusion was quite tricky. As there was no understanding of blood groups, blood transfusions were extremely risky. Sometimes they were successful: in 1818 James Blundell managed to accomplish the first successful human blood transfusion, and saved a woman hemorrhaging from childbirth. Other people, nonetheless, simply went into shock and died after claret transfusions.
Some scientists attempted to prevent the adverse reactions to claret transfusions past transfusing blood substitutes. The transfusion of moo-cow's milk was attempted in 1854 in Canada, during a cholera epidemic. Drs. Bovell and Edwin Hodder started intravenous transfusions of milk in the belief that the fat molecules in milk could exist transformed into white claret cells, and that white blood cells were an young version of cerise claret cells. This belief was erroneous, of course, but they had success with 1 sick man who responded favorably to the transfusions. Two other patients, however, died subsequently milk was transfused into their veins.
These experiments were discontinued in Canada shortly afterward the cholera epidemic, but were revived in New York City a few years after. Using goat's milk this time, Dr. Joseph Howe transfused patients suffering from final tuberculosis. The patients all demonstrated nystagmus (shaking eye movements) and chest pain, and all of the patients died a few hours after transfusion.
Despite the lack of obvious benefit, milk transfusions continued in the late 1880'south, as the use of blood was discouraged since information technology had a tendency to coalesce. As more patients died from milk transfusions, the practice fell out of favor. In the 1880's, isotonic saline solution was invented, and the use of milk savage entirely out of favor in favor of the new, rubber saline solution. The revival of blood transfusions would accept to wait for the 20th century, when a new era of microbiology ushered in the understanding of various blood groups and compatibility.
In 1901, an Austrian doctor named Karl Landsteiner recognized the 3 basic blood groups – blood was kickoff cantankerous matched in 1907. Blood storage was withal a problem during the early on days of claret transfusion – while the compatibility issues had been resolved, blood still had a tendency to clot during storage. Anticoagulants similar sodium citrate were developed in the year 1914, allowing blood storage for an extended period of fourth dimension. The discovery of Rh factor in 1940 allowed doctors to completely understand the compatibility issues amidst blood donors and recipients, and the American government started its kickoff national blood collection program soon thereafter.
Claret Typing Video
Claret Type Tests and Claret Transfusions
A traumatic auto accident has occurred, and a severely injured patient is rushed to the emergency room. As the patient lies bleeding, doctors scurry to take a sample of the patient's blood and have it sent away to be typed and cantankerous-matched.
In the laboratory, a technician applies the claret to a special carte du jour, which contains antibodies to the A and B blood groups. If the patient'south blood clumps around the A antibody, this means they accept the B antigen and it is attacking the A antibody. If the patient's claret clumps effectually the B antibiotic, then the patient has the A blood type. If the patient's blood clumps around both the A and the B antibiotic, they have the O blood type, and if the patient's blood doesn't react to either the A or B antibodies, then he or she has the AB claret type.
In the example of our patient, the blood clumps around both the A and the B antibodies. The patient has the O claret type. An Rh test is also performed, and our patient is positive for this protein.
Equally determined past this exam, the patient needs a transfusion of type O+ or O- claret. The blood bank releases type O+ blood for utilise, and the patient is and then cross-matched to be sure there are no adverse reactions.
The sample of the O+ claret is taken from the blood bank and mixed with the patient's blood in a test tube. The sample is watched for any adverse reaction, and if no clumping is noted, the blood is safe for the patient to utilise. The sample demonstrates no reaction with our patient's claret, and so the bag of donated, O+ blood is rushed down to the waiting patient. As claret is transfused, the patient's vital signs improve.
Claret Types and Compatibility
The AB+ blood type is known every bit the Universal Receiver: an individual with this blood type tin can receive whatever other blood type without reaction.
The AB- blood blazon may receive blood types A-, B-, or O-; any transfused blood must be Rh negative to avert reaction.
The A+ blood type may receive claret types A+, A- , O+, or O-.
The A- claret type may receive blood types A- and O-.
The B+ blood type may receive blood types B+, B-, O+, or O-.
The B- blood type may receive blood types B- or O-.
The O+ blood type may receive blood types O+ or O-.
The O- blood type may only receive the O- claret type. People with O- blood are known as Universal Donors, as their blood will not cause a reaction with any other claret type when donated, since the blood lacks all surface antigens and will not provoke an immune system attack in the receiver.
Blood Compatibility and Rh Factor
Blood Blazon Complications: Rh Factor in Pregnant Women
For most people, claret type is of little consequence in life. Sometimes, however, a woman is Rh negative and becomes pregnant with a baby who is Rh positive. If this is the first pregnancy, the baby is unremarkably fine because the mother's claret doesn't mix with the infant'southward during the gestational period. Sometimes, even so, the baby'south and mother'south blood mixes during delivery. The female parent'southward immune system then begins to mountain a defence force confronting the foreign protein.
When the female parent gets pregnant for the second fourth dimension with an Rh positive baby, the risks are much higher. In this example, the mother's immune system may react to the foreign Rh protein carried by the baby. When this happens, the mother'south immune organisation attacks the baby's red blood cells, causing them to rupture. The baby develops a form of hemolytic anemia, which can be fatal.
To forbid harm to the babe, the mother can exist given injections of Rh immune-globulin. The Rh immune globulin is an antibody for the Rh factor: if any of the infant's claret has made its way into the mother's system, the Rh allowed-globulin binds to the infant's blood cells. These "borrowed" antibodies volition prevent the female parent's immune system from producing her own.
If a mother demonstrates high levels of Rh antibodies in her blood organisation, the baby is carefully monitored. If the baby shows signs of distress, a process known as an substitution transfusion is sometimes performed to replenish the babe's blood supply.
Blood Type Inheritance
Inheritance patterns of the ABO blood groups - A and B are codominant, so those who inherit type A and type B alleles will have type AB blood. Those with types AO or BO volition exist type A or B, respectively.

Blood Type Genetics
Blood types A and B are co-dominant, so if the father has blood blazon AA and the female parent has blood blazon BB, the child will accept a claret type of AB.
Blood Blazon O is recessive, and then a child will only have this claret blazon if he or she gets 2 O blood type genes from his or her parents. If both parents are blood blazon O, all of the children in the family unit will have the O blood blazon. Another way this tin can happen is if the parents are heterozygous for the O allele: this means the female parent may be claret type A, but her genotype (the genes she carries) are really AO. In this example, she expresses the A claret antigen, simply she also has a factor for the O blood type. If she marries another heterozygote AO carrier, there is a chance that one of their children would inherit both O genes and so accept the O blood blazon. The chance of this family unit having a child with the O blood blazon is 25% - there is a 50% chance they would have a child with the AO genotype (which would take the A blood type) and a 25% gamble they would have a kid with the AA genotype (A blood type).
Blood type A is dominant over blood type O, so anyone who has one A gene will have the A claret type, even if they carry one type O cistron.
Blood type B is dominant over claret blazon O, so anyone who has one B gene volition have the B blood type, fifty-fifty if they carry i type O gene.
Rh cistron is dominant, then a parents who are accept two alleles for Rh factor will have children who are Rh positive. If the parents are heterozygous (having ane Rh factor allele and 1 Rh negative allele), they have a 25% chance of having an Rh negative child. If both parents are Rh negative, all of their children volition be Rh negative.
Questions & Answers
Question: How did I get an AB+ claret type?
Respond: Claret types A and B are co-dominant, then if you lot inherit the A blood blazon from i parent and the B blood blazon from another parent, information technology is quite possible to accept blazon AB blood. The positive Rh factor is fairly common and is inherited separately from the AB type.
Question: You said claret type A is dominant over O. I'1000 A- and my son is O+. I don't know what claret type his dad is, though. Do you know if my son is recessive rh-? Does this mean I am recessive rh+?
Answer: The positive Rh trait is e'er dominant. Since you are A-, that means you have two Rh negative alleles. Your son'southward father is most likely type O+ claret. You carry an O allele (so your genotype would be A- O-). In your instance, the O is recessive and and so you only display the physical feature of the A blood type. Your son inherited 1 copy of the O gene from you lot and from his male parent. He inherited i negative Rh gene gene from yous and one positive Rh factor from his father, so he displays the Rh positive phenotype (since the positive gene is dominant).
Question: What percent of African Americans have type A blood?
Answer: According to the American Red Cantankerous, approximately 26% of African Americans have type A claret. Of this percent, 24% are A+ and ii% are A-.
Question: I recently discovered through our family's research that all of the men on my father's side all had/have O- blood. I'thousand the son of a genetically identical twin and the other twin had twin boys with O+ blood. First can y'all explain why all of the men in my lineage have O-claret? And why are my aunt's son O+? My parents were also O-.
Answer: The negative Rh gene is recessive, and then it is likely that your female parent and father were both negative. Your uncle was an identical twin to your father, which ways he was too negative. If your uncle married a woman with a positive gene, and so at that place would be a fifty% gamble of each child having a positive factor at birth, and a 50% chance of having a negative factor. The positive gene is dominant.
Question: My mum, my sister and myself have A- claret, simply my younger sis has AB. What blood type would our father take had?
Answer: Your father probable had Type BO blood. If your mother is type AA and your father is type BO, and so the combinations would have resulted in a fifty% chance of having type A claret (AO genotype, simply O is recessive) and a fifty% chance of having type AB blood (the A and B types are co-dominant and will limited themselves at the same time).
Question: My mom, dad, and sis take type O negative blood, but I have a positive Rh factor., is this possible?
Answer: In general, the negative Rh factor is a double recessive gene. If both of your biological parents are Rh-negative, then you should also accept a negative Rh factor.
Question: My mom is O positive and my father was A positive, just I'm O negative, how is this possible?
Respond: This would be possible every bit blazon O is recessive, along with the negative blood type. In this case, your female parent would be O+O- and your father would be A+O-. While they demonstrate only the dominant form of each cistron (the positive Rhesus factor for both and the A claret blazon for your father), each one carries the O- gene and passed it on to yous.
Question: Tin can a babe go the Rh negative blood type from a grandparent if both parents are positive?
Reply: The Rhesus gene is a recessive trait, so a baby can inherit a negative Rh factor if both parents are positive heterozygotes. In this scenario, we could suppose that a grandparent is Rh negative, but has a husband who is Rh positive. Their kid would likely exist Rh positive, but would carry the gene for a negative rhesus cistron (this is called a heterozygote - they behave the cistron just exercise not express the trait). If this child grew up and married some other heterozygote, they would accept a 25% probability of having a baby that is Rh negative, a 50% chance of having a child who is Rh positive and a carrier of the negative gene, and a 25% gamble of having a kid who is positive and does non carry the negative factor at all.
Question: My blood type is AO, and my children's father is blazon O. How does my son have type AB?
Answer: I cannot explain how your child has type AB blood if his biological father has type O blood. Type O blood is double recessive. With a mother having AO blood and the male parent having OO blood, the possible combinations are AO, AO, OO, and OO. Your children would accept a 50% risk of having blazon A blood (the AO genetic type) and a l% chance of having type O claret (the OO genetic type).
Question: What does it mean if my mother is RH- claret type and I'grand O- blood type? What does this say about me?
Answer: Your female parent'south Rh gene is negative, and so is yours! You don't give your mother'due south claret type, which is typed as a letter (A, AB, B, or O). The O blood type is recessive, so for someone to have the O claret type, they demand ii recessive "O" genes. Your female parent could be A, B, or O since many people who are type A or B acquit an O gene (A and B are dominant over O).
Question: I have A+ blood. My male parent was of Sicilian descent. My mother was of High german and Irish gaelic descent. Is A+ blood blazon compatible with my genealogy?
Answer: Aye, the A blood type is compatible with your ancestry. The A blood blazon is ascendant and is found throughout Europe.
Question: My dad is Syrian with type O+ and my mom is African mixed with Indian and carries B+ however my sis and I bear type AB+. How is that possible?
Answer: Information technology would non exist theoretically possible for a parents with type O and blazon B to produce children with type AB blood.
Question: I accept type O, RH positive so are my parents the same blazon?
Answer: Your parents may non have the same claret blazon you practise. The O blood type is double-recessive, so your parents could be blazon A, type B, or blazon O and still accept a kid with an O blood type.
Question: I take AB blood. My father'south side all have O blood and my mother'due south side all have O blood. Is it possible for 2 type O parents to have a child with blood type AB?
Answer: It is highly unlikely that ii parents with Blazon O blood would produce a child with an AB blood type. Since the O claret blazon is double recessive, your parents each have OO and OO, which would outcome in all children having type O blood. To obtain Blazon AB, one parent must accept Blazon A, B, or AB claret and the other parent must also have blazon A, B, or AB blood.
Question: In what part of the world is Rh negative claret type near commonly institute?
Answer: Australia has the highest percentage of Rh negative blood, with approximately 19% of the population demonstrating a negative cistron. The Basque population in Espana has the highest percentage of Rh negative blood as an ethnic group, with 21-43% of Basque people demonstrating the negative cistron (dependent on location).
Question: I accept blood type B+ but my mother is from Frg. Is my blood blazon compatible with my genealogy?
Reply: Yeah, it is possible to take type B+ blood with German language ancestry. There has been a lot of migration and movement throughout homo history, and currently 11% of Germans have type B blood (nine% have type B+ and ii% have type B-).
Question: If I am AB+ what were my parents?
Answer: Your parents might both be blazon AB, one parent might be type AB and the other might exist type A, one parent might exist type AB and the other blazon B, or y'all may have 1 parent that is type A and 1 parent that is type B. Any of these combinations could produce a child that is type AB.
For the + Rh factor, both of your parents are Rh positive.
Question: What is the youngest blazon of blood in humans?
Answer: According to the BBC, type AB is the most contempo blood type in humans. While the O blood type is universally compatible, it is not likely to exist the oldest blood type among humans. Both the A and B types may become O with a few mutations, so it is probable that A is the oldest, followed by O or B. There are competing theories on blood blazon and evolution. Each type varies by geographical region and ethnicity.
Question: Why is Africa excluded from your commodity's world analysis?
Answer: Africa is not excluded from this world assay. The list of blood blazon percentages merely lists the continent where each blood blazon is the almost common. In this synopsis, Type A has the highest prevalence in Europe and Central Europe, Blazon O has the highest prevalence in the Americas, Type B and Type AB have the highest prevalence in Asia.
Blazon O+ blood is the most common across the continent of Africa, but it does not take the highest prevalence in the world of this blood type. 45% of South Africans have Type O blood, but this is not the highest prevalence (nearly 100% of South Americans have Type O blood). In short, the claret types across the continent of Africa are varied and it does not have the highest prevalence of whatsoever ane blood blazon.
Question: I am an A+ claret type and I desire to become married. Which blood group should I marry?
Respond: You lot should non consider someone else'due south blood type when you are considering a future spouse. Blood blazon has no bearing on wellness or general compatibility.
Question: What is the virtually mutual blood type in Sweden?
Answer: The near common claret type in Sweden is A+. Approximately 37% of the population has this blood type. The second most common blood type in Sweden is O+.
Question: Can an A- person ever accept 2 parents each with O+ blood type?
Respond: A person may inherit a negative Rh cistron from two parents with a positive gene, if each parent is heterozygous for this trait. If the mother is +/- and the father is +/-, each volition have a phenotype (physical characteristic) of having a positive Rh factor while however carrying the negative Rh factor gene. Each child would have a 25% chance of inheriting both Rh - alleles and demonstrating that phenotype. Two parents with type O blood, notwithstanding, would not have a biological child with type A blood. Blazon O blood is double recessive.
Question: What percentage of African Americans have type B blood?
Answer: eighteen% of African Americans have type B+ blood, and 1% accept B-. Excluding Rh cistron, nineteen% of African Americans carry this blood type.
Question: My wife and I have are A/B-, what blood type will our child have?
Respond: Your child's rH factor will be negative, as you and your wife are both negative for this cistron. The child's blood type will depend on which genes they obtain. The A and B blood types are co-ascendant. Your child may obtain the A gene from both parents (25% chance of A- claret blazon), the B factor from both parents (25% chance of B- phenotype), or i of each (50% risk of AB-).
Question: What percentage of African Americans have type A- blood?
Answer: According to the American Red Cross, only two% of African Americans have type A- blood. This would be a rare blood type for this demographic.
Question: I'k from the Cape verde Islands off the west coast of Africa. I accept AB+ blood. Is this normal?
Answer: Co-ordinate to The Distribution of ABO Blood Grouping Organisation In Porto Novo District Of Greatcoat Verde Islands, a research paper past Peter Okeke in 2009, the post-obit blood types were observed (from 750 samples):
320 people were Type O (43%)
226 people were Type A (30%)
167 people were Type B (22%)
37 people were Type AB (5%)
Having Type AB blood is rare, only not unheard of among the Cape Verde population.
Question: Tin can a person accept blood type ABO positive ?
Answer: A person could exist type AB or type O, but not type ABO. If a person carried the genotype for blazon AO or type BO, they would but express the blood type as type A or type B, every bit the O blood type is recessive. To demonstrate type O blood, yous must have both copies of the gene.
Question: What percentage of African Americans accept blazon AB- blood?
Reply: 0.three% of African Americans have type AB- blood.
Question: I have a B+ blood type. My girl is O+ and my son is B+. My husband forgot his blood blazon. Can you figure what blood type my husband is?
Respond: The but manner to actually know what blood blazon your hubby is would be to have information technology typed. The only thing we know for sure is that yous and your married man each conduct a cistron for the O claret type, which is recessive. You likely carry 1 factor for B and one for O (B is dominant so your blood type is B). Your husband could be AO (A blood type), BO (B blood type), or OO (O blood type). Your girl would accept inherited one O allele from each of you, resulting in her double-recessive blood type. If your husband would like to know his blood type, he should have it typed, equally it is incommunicable to know from your children's profiles.

I have AB, my dad was O- and my mom is O- is it possible for bloodtype O to have a child with blood blazon AB
Carol Walker on August 15, 2019:
I have AB-, my Dad was O-. Is there any way I can find out where negative RH came from within the family? (
Leah Lefler (author) from Western New York on August 12, 2019:
It is important to realize the Rh type and blood blazon are not linked. Type O blood is the most mutual blazon of blood in the U.s. with a positive Rhesus factor. The negative Rh does make O- blood rarer than O+ blood, but it is still not the rarest blood type. AB- is the rarest, followed by B-, then AB+, then A-. Approximately 6.6% of the US population has blazon O- claret, Stan, so it is non extremely common, simply also not rare. The highest prevalence of O- claret is institute in Espana and the Uk (ix% of the population), though many countries in Europe have a prevalence betwixt half-dozen-9% of the population. Argentina also has a very high relative prevalence of people with the O- blood type.
Stan on Baronial 12, 2019:
Does blood type tells usa something about our ancestry. I read where O negative is rare except among the Basque population of Iberia and the Celtic tribes of Britain. How likely is O negative blood type connected with Scottish or Basque beginnings?
Leah Lefler (author) from Western New York on May 08, 2019:
It is probable your father'southward genotype is heterozygous, which means he carries one allele for B and 1 allele for O. Yous inherited the B from your male parent and an O from your mother - since B is ascendant, yous take the B blood type. Your sis would have inherited the O from your father and an O from your mother, making her blood blazon O.
Tina on May 06, 2019:
My father is b+ and mother is o+. But, why is it that i have my fathers claret type and my sis has our mothers blood type.
Leah Lefler (author) from Western New York on February 06, 2019:
The O blood type is recessive, Reina, and so your female parent and father both carried the O allele and you happened to go both copies. Your blood brother'due south male parent also carries the recessive gene for the O blood type, and he carries the aforementioned blood blazon (despite having a different father). Your parents could have type A, B, or O blood and however have a child with type O, since the trait is recessive. The negative Rh factor is also recessive.
Reina on February 02, 2019:
I am O negative and my two brothers. One of my brothers has a different father but we have the same female parent. How is information technology that we have same female parent, different begetter still have szmd blood type( O negative)?
EmG on April 20, 2017:
I am o positive and considerd African American in America. I was always told about having Indian ancestors on both sides. My mother is O as well and my father is A. Shouldn't this exist proof that many African Americans are classified incorrectly in ethnicity and racial classifications. Many of the states have hard time claiming our rights as ancient people. What tin we do to change this and let people know who they are. The African American has been looking for their ancestral past for generations and this can definitely shed light on giving u.s. our missing slice to our heritage puzzle. Thank you!
Leah Lefler (author) from Western New York on June 14, 2015:
B positive is definitely a rare claret type! The nigh mutual blood blazon in the world is type O blood. I really know someone with type AB+ blood, Anya - I always tell him how rare that is!
Anya on June 11, 2015:
I am B pos
Information technology is not a common blazon despite what people say
information technology is a actually a rare Rh pos blood blazon merely 8 to 9 percent of people have this blazon
The rarest Rh pos type is AB pos which is 2-3% of people
Leah Lefler (author) from Western New York on January 22, 2015:
Carmel, there are genetic testing kits available online for tracing ancestry through the Y chromosome. Type "Y-Dna" testing kits into google and you lot will likely be able to decide the general ancestry using just your son'due south sample. Otherwise, a standard paternity test (also available online) volition work, but yous volition need a sample from your partner and from your son to determine if your partner is his biological father.
carmel on January 22, 2015:

It is interesting, isn't it? Kariannr, I wonder if the percentages will change over fourth dimension, as people are very mobile at present. My own family has a lot of A blood types, but my aunt is O negative - she got the recessive genes the whole style circular!

I thought that was actually interesting how you explained different races having unlike percentages of negative Rh factor and the different countries where the different blood types are more common. I know that probably sounds really dumb, simply I'chiliad a medical laboratory science educatee, and any new information is awesome to me.
