IAIB

Detailed explanation-1: -The phenotype type of the genotype blood IAIB is AB. This is consistent with answer choice “C". Similar to O type blood, there is only one possible genotype type. This is because AB blood type is co-dominant meaning both alleles are expressed equally and there is not a masked allele.
Detailed explanation-2: -Final answer: A person having genotype IA IB would show the blood group as AB. This is because of codominance.
Detailed explanation-3: -Individuals with IAIA or IAi have to type A blood, and individuals with IBIB or IBi have type B. IAIB people have both phenotypes because A and B express a special dominance relationship which is known as codominance. So, it means that type A and B parents can have an AB child.
