Detailed explanation-1: -Type A, in which only the A antigen is present. Type B, in which only the B antigen is present. Type AB, in which both the A and B antigens are present. Type O, in which neither the A nor the B antigen is present.
Detailed explanation-2: -There are 4 main blood groups (types of blood) – A, B, AB and O. Your blood group is determined by the genes you inherit from your parents.
Detailed explanation-3: -Blood Type Is Determined Genetically The A allele codes for an enzyme that makes the A antigen, and the B allele codes for an enzyme that makes the B antigen. A third version of this gene, the O allele, codes for a protein that is not functional; it makes no surface molecules at all.
Detailed explanation-4: -The types of proteins, glycoproteins and glycolipids found (or expressed) on the surface of red blood cells define blood types. In addition, blood types, or at least the genes responsible for them, are inherited.
