What blood type is ”AO”?

Question

I don’t think it exists, but some people say it does….?

Tiana Kshlerin · Accepted Answer

You are right It is a genotype not blood group. The blood group is the phenotype. People with the genotype AO have an A allele and O allele but are classed as blood group A. This is because the O allele does not produce an antigen but the A allele produces the A antigen. Therefore AO genotypes produce just A antigens and so the individual is classed as group A. Hope that makes sense.

Blood Type Ao

Tiana Kshlerin · Answer

AB parent can only pass off A or B AO parent can only pass of A or O So, the combinations are AA, AO, AB, and BO. AA and AO are both expressed as type A blood because A antigens are present regardless of the O alelle. Similarly, BO is expressed as type B blood because B antigens are still present. The O phenotype type only exists from a OO combination, where no antigens exist. So the possibilities are A, B, AB.

The only way to know if you are AO is if you have a child that turns out to be an O. This means you give one O gene and the father gives one O gene. O is sort of recessive in that it means there is no A or B antigen on the RBC. There is no way to detect AO or BO by testing only that they will appear to be an A or B blood type.

I think they mean this:People with blood type O have a genotype of “ii,” which are recessive. Blood type A can either have a genotype of “AA” (dominant genes), OR, they can have a combination of “A” and a “i”, which would make “Ai”. This is still blood type A as the “A” is dominant over the recessive “i” gene that makes up blood type O.I hope this is what they mean.

Tiana Kshlerin · Answer

If one parent has the blood type AA and the other has the blood type OO the offspring have a chance of recieving AO blood
