a.
To determine: The possible genotypes of the individuals with blood group A.
Introduction: The human blood group is an example of codominance where the alleles for the two antigens A and B are equally dominant. This means that when the two antigens A and B are present the blood group is AB while in the absence of both the antigens the blood group is O.
