The human ABO blood group system exhibits codominance. The system consists of three alleles A, B, and O. Both A and B are dominant in relation to O, and therefore blood group A can have the genotype AA or AO.
Is blood type an example of incomplete dominance or codominance?
® Blood types are A, B, O, and AB. ® AB blood is a co-dominant trait. co-dominant blood types, which is AB. Human blood type is an example of both codominance and a trait with multiple alleles.
Are blood type A and B codominant?
The A and B alleles are codominant. Therefore, if an A is inherited from one parent and a B from the other, the phenotype will be AB. Agglutination tests will show that these individuals have the characteristics of both type A and type B blood.
