The genotypes of a husband and wife are `I^(A)I^(B)` and `I^(A)i`. Among the blood types of their children, how many different genotypes and phenotypes are possible?

Options

A. 3 genotypes , 3 phenotypes
B. 3 genotypes , 4 phenotypes
C. 4 genotypes , 3 phenotypes
D. 4 genotypes , 4 phenotypes

Answer

C

Explanation

A cross between two individuals, one with AB blood group and other with A blood group will produce four genotypes and three phenotypes

Offsprings Genotypes : `4(I^(A)I^(A),I^(A)I^(B), I^(A),i,I^(B)i)`
Phenotypes : 3 (A, B, AB)
