Q. In blood group typing in human, if an allele contributed by one parent is $I^{A}$and an allele contributed by the other parent is i, the resulting blood group of the offspring will be
A) A
B) B
C) AB
D) O
Explanation
The blood group type in human provides an example of multiple allelism (i.e., presence of more than two allele for one gene). There are three A, B and O blood groups allele usually given the symbolI , I and I ୧ .I and I are codominant to each other but both are dominant to I ୧ . The offspring of parents having I and I1 allele with be I I୧ having blood group-A. A-I I୧ B-I I ୧ AB-I I O-I ୧ I ୧
