Explanation:
Detailed explanation-1: -Both A and B alleles are dominant over O. As a result, individuals who have an AO genotype will have an A phenotype. People who are type O have OO genotypes.
Detailed explanation-2: -Note: Blood group A is divided into two main phenotypes, A1 and A2 (1).
Detailed explanation-3: -The term “homozygous” is used to describe the pairs “AA” and “aa” because the alleles in the pair are the same, i.e. both dominant or both recessive. In contrast, the term “heterozygous” is used to describe the allelic pair, “Aa”.
