Vedclass · Answer

(C) The blood group of the child is $O$,which means the genotype of the child is $I^O I^O$.This implies that the child must have inherited one $I^O$ allele from the mother and one $I^O$ allele from the father.Since the father has blood group $B$,his possible genotypes are $I^B I^B$ (homozygous) or $I^B I^O$ (heterozygous).Because the child inherited an $I^O$ allele from the father,the father must possess at least one $I^O$ allele.Therefore,the genotype of the father must be $I^B I^O$.

$A$ child of $O$ blood group has a $B$ blood group father. The genotype of the father will be:
