Detailed explanation-1: -Due to codominance of IA and IB alleles, the genotype A and IB produce “AB” blood group. Thus, the six genotypes give total four phenotypes. Hence, parents with A and B blood group can have child with A, B, AB and O blood groups. Thus, the correct answer is option D.
Detailed explanation-2: -If a baby’s and mother’s blood are incompatible, it can lead to fetal anemia, immune hydrops (erythroblastosis fetalis) and other complications. The most common type of blood type incompatibility is Rh disease (also known as Rh incompatibility). The Rh factor is a protein on the covering of red blood cells.
Detailed explanation-3: -An AB parent can indeed sometimes have an O child. But it is by no means common. In fact it would be fair to say that it is exceedingly rare. Usually, an AB parent and an A parent can only have children who are Type A or Type B.
