A fairly easy-to-understand example is that of the ABO blood group system. In this case, there is a single gene involved - ABO, which codes for an enzyme that modifies sugar groups on the surface of red blood cells. This ABO gene has three variants or alleles — i, IA, and IB. i (coding for Type O blood) is recessive, which means ...
