This question refers to the abo blood type locus. remember that the a and b alleles are codominant to each other and both are dominant to the o allele. a man has blood type

a. mark all genotypes below that are possible for this man.

The man with blood type A might have one of two genotypes:

1. Iᵃ Iᵃ

2. Iᵃ i

In this case, Iᵃ is an allele for A group, and i is an allele for 0 group.

The ABO blood type is controlled by a single gene (the ABO gene) with three types of alleles (Iᵃ Iᵇ and i)
