The genotypes of a Husband and Wife are I ^ A I ^ B and I ^ A i ....

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?

Step-by-step solution

$\begin{cases}\text{Husband} & \times & \text{Wife} \\ {\text{I}}^{\text{A}} {\text{I}}^{\text{B}} & & {\text{I}}^{\text{A}} \text{i}\end{cases}$



Number of genotypes = 4

Number of phenotypes = 3

${I}^{A}{I}^{A}$ and ${I}^{A}i = A$

${I}^{A}{I}^{B} = AB$

${I}^{B}i = B$
