A person has one of the four blood groups: A, B, AB or O. This blood group system is controlled by a gene which has three different forms denoted by the symbols IA, IB and IO. The genes IA and IB show no dominance over each other, that is, they are co dominant. However, genes IA and IB both are dominant over the gene IO.
