A person with genotype AB has type AB blood, and a person with genotype OO has type O blood. A person with type A blood cannot receive type B blood. The reason is immunological. A person with type A blood does not have type B antigens; thus, his immune system considers the type B antigen to be foreign and attacks it.A person with type A blood can't receive type AB blood, either, for the same reason. He can, however, accept type O blood. person with type A blood cannot receive type B blood. The reason is immunological. A person with type A blood does not have type B antigens; thus, his immune system considers the type B antigen to be foreign and attacks it.
The rarest phenotypic blood type is Type AB negative found in only 0.7% of people worldwide. Genetically the rarest blood type should be Type O; however, it's the most common blood type. There is more to ABO blood typing that just the ABO gene.There is also an inhibitory gene that will change any genotype into the phenotype O. Therefore a person with genetically AB blood can be tested as having Type O. positive O negative A positive A negative B positive B negative AB positive AB negative The rarest of all these blood types listed is AB negative making up 0.7% of â¦ the worlds population.
