The mother has A+ blood group the father has B+ and the child is A+...

The child blood group is $\left(\mathrm{A}^*\right)$ that means he must have received ( $i$ ) allele from the father i.e. the father genotype is \left(I^B I\right)$. While mother can have$\mu^\mu \mu^\mu or $\mu^A$ genotype. So, the possible genotypes of all three i.e. mother, father and child respectively would be either (B) $I^A I^A\left|I^B i\right| I^A i$ (E) $I^A i\left|I^B i\right| I^{A_i}$
