Multiple alleles refers to a situation in which there are more than two alternative forms of a given gene. This is common in populations of organisms where variations exist in the frequency and distribution of different alleles. As a result, there may be multiple forms of a given trait in the population, each determined by a different allele combination. Examples of multiple alleles include the ABO blood group system in humans, where there are three alleles (IA, IB, and i) that determine blood types.
