Answer:
Codominance
Explanation:
The mode of inheritance of the ABO blood types is the representative of co-dominance. In ABO blood type three types of alleles are present IA, IB, and i. IA and IB are dominant and i allele is recessive.
So when two dominant alleles IA and IB come together they both are co-dominantly expressed in the offspring and the blood group of the offspring becomes AB. This is the reason the ABO blood group is an example of co-dominance.
