Medical Definition of Polymorphism

1. 1. The regular and simultaneous occurrence in a single interbreeding population of two or more alleles of a gene, where the frequency of the rarer alleles is greater than can be explained by recurrent mutation alone (typically greater than 1%). The concept includes chromosome polymorphism. HLA alleles of the major histocompatibility complex are very polymorphic. 2. The differentiation of various parts of the units of colonial animals into different types of unit specialised for different purposes, for example as in the colonial hydroid Obelia. (04 Jul 1999)
