Answer : a

Hints & Solutions

(a) The inheritance of blood group is determined by some allelic genes which are $I^{A}$ , $I^{B}$ & $I^{\circ}$ . In one individual, two allelic genes are present. $I^{A}$ & $I^{B}$ are dominant, while $I^{O}$ is recessive in the heterozygous condition. So, if a child has a blood group $O$ , he/she must have $I^{\circ} I^{\circ}$ and he/she cannot have the parents of blood group $A B$ & $A B / O$ .
