Mother and father of a person with ‘O’ blood group have ‘A’ and ‘B’ blood group, respectively. What would be the genotype of both mother and father?
a. Mother is homozygous for ‘A’ blood group and father is heterozygous for ‘B’
b. Mother is heterozygous for ‘A’ blood group and father is homozygous for ‘B’
c. Both mother and father are heterozygous for ‘A’ and ‘B’ blood group, respectively
d. Both mother and father are homozygous for ‘A’ and ‘B’ blood group, respectively
The answer is the option (c) Both mother and father are heterozygous for ‘A’ and ‘B’ blood group, respectively
Explanation: Offspring ii (O blood group) is the feasible phenotype of parents and IAi (A blood group) and IBi (B blood group) are the feasible genotype of the parents.
