Explanation:
Detailed explanation-1: -If parents have blood groups A and B, their genotype will be IA i and IB i. Thus, the next generation will have: IA i (A blood group), IA IB (AB blood group), IB i (B blood group), ii (O blood group). Thus there is a chance of one child with O blood group out of 4.
Detailed explanation-2: -Due to codominance of “IA” and “IB” alleles, the genotype “IAIB” produce “AB” blood group respectively. 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. Correct option is “C".
