Answer

ABO blood type is determined by the combination of antigens and antibodies in the blood. This combination is determined by an individual’s heredity. The four types of blood are Type A, Type B, Type AB, and Type O. Type A blood contains Type-A antigens and anti-B antibodies. Type B blood contains Type-B antigens and anti-A antibodies. Type AB blood contains both Type-A and Type-B antigens and no antibodies. Type O blood contains no antigens and both Type-A and Type-B antibodies.
