Detailed explanation-1: -The four basic ABO phenotypes are O, A, B, and AB.
Detailed explanation-2: -People who are type O have OO genotypes. In other words, they inherited a recessive O allele from both parents. 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.
Detailed explanation-3: -The possible human phenotypes for blood group are type A, type B, type AB, and type O. Type A and B individuals can be either homozygous (IAIA or IBIB, respectively), or heterozygous (IAi or IBi, respectively).
Detailed explanation-4: -Someone with blood type O has neither the A nor the B allele. The genotype must be OO.
Detailed explanation-5: -There are four hemoglobin genotypes (hemoglobin pairs/formations) in humans: AA, AS, SS and AC (uncommon). SS and AC are the abnormal genotypes or the sickle cells. We all have a specific pair of these hemoglobin in our blood which we inherited from both parents.
