Quizplus · Accepted Answer

A gene that has three or more alleles is called a multiple allele system. This means that there are more than two possible versions of the gene within a population. Examples of multiple allele systems in humans include the ABO blood type system, where there are three alleles (A, B, and O) that determine blood type, and the human leukocyte antigen (HLA) system, which has many alleles and plays a role in immune function.
