Vedclass · Answer

(D) The blood group of the mother is $O$,which means her genotype is $ii$.The blood group of the father is $A$. The genotype of the father can be either $I^A I^A$ (homozygous) or $I^A i$ (heterozygous).Case $1$: If the father is $I^A I^A$,the cross is $ii 	imes I^A I^A$,resulting in offspring with genotype $I^A i$ (Blood group $A$).Case $2$: If the father is $I^A i$,the cross is $ii 	imes I^A i$,resulting in offspring with genotypes $I^A i$ (Blood group $A$) and $ii$ (Blood group $O$).Therefore,the possible blood groups for the child are $A$ or $O$.

$A$ child with a mother of $O$ blood group and a father of $A$ blood group will have which of the following blood groups?
