The correct answer is:
Both mother and father are hetrozygous for ' A' and 'B' blood group respectively
Both mother and father are hetrozygous for ' A' and 'B' blood group respectively
(c) When a cross is carried out between heterozygous father (for blood group B) and heterozygous mother (of blood group A) to get four children with different blood groups.
All the four blood group are controlled by three allelic gene IA, IB, i and thus it shows phenomenon of multiple allelism, Both IA an IB is dominant overi However, when both the alleles are dominant and show the phenomenon of codominance, forming the blood group $\mathrm{AB}$, six genotypes are possible with conbination of these three alleles. Thus, other options are incorrect.
