Cross-species summary:
Each blood group system consists of a set of blood types, each of which corresponds to a particular antigen (usually a glycoprotein) on the surface of red blood cells. The different types within a system are the result of the action of different alleles at a locus that usually encodes an enzyme that catalyses the creation of the feature of the glycoprotein unique to that type, e.g. the presence of a particular sugar at the end of a short chain of sugars.
The ABO blood group system arises from two alleles at a locus that encodes a glycosyltransferase: the A allele encodes alpha 1-3-N-acetylgalactosaminyltransferase; and the B allele encodes alpha 1-3-galactosyltransferase. The B allele transferase catalyses the addition of galactose to a chain of four sugars attached to a protein known as H antigen. The A allele ltransferase catalyses the addition of a derivative of galactose called N-acetylgalactosamine to the same short chain of sugars. The third allele at this locus (the O allele) results in no sugar being added to the chain.
