(D) The blood group $A$ can be represented by genotypes $I^A I^A$ (homozygous) or $I^A i$ (heterozygous). The blood group $AB$ is represented by the genotype $I^A I^B$.If the man is homozygous $(I^A I^A)$,the cross is $I^A I^A 	imes I^A I^B$,resulting in offspring with genotypes $I^A I^A$ (Group $A$) and $I^A I^B$ (Group $AB$).If the man is heterozygous $(I^A i)$,the cross is $I^A i 	imes I^A I^B$,resulting in offspring with genotypes $I^A I^A$ (Group $A$),$I^A I^B$ (Group $AB$),$I^A i$ (Group $A$),and $I^B i$ (Group $B$).The presence of an offspring with blood group $B$ $(I^B i)$ confirms that the father must have contributed the $i$ allele,meaning he is heterozygous $(I^A i)$.

$A$ man with blood group $A$ marries a woman with blood group $AB$. Which type of offspring would indicate that the man is heterozygous for blood group $A$?
