Vedclass · Answer

(A) The inheritance of $ABO$ blood groups is controlled by the gene $I$. The gene $I$ has three alleles: $I^A, I^B,$ and $i$.If the man is heterozygous $(I^Ai)$ and the woman is heterozygous $(I^Bi)$,the cross is $I^Ai 	imes I^Bi$.The possible genotypes of the offspring are $I^AI^B$ (blood group $AB$),$I^Ai$ (blood group $A$),$I^Bi$ (blood group $B$),and $ii$ (blood group $O$).Therefore,the maximum possible blood groups among their children are $A, B, AB,$ and $O$.
