multigene family


Also found in: Encyclopedia, Wikipedia.

multigene family

A family of sequence-related genes within a genome which evolved from a single ancestral gene by gene duplication and subsequent mutations.

multigene family

A collection of genes, usually but not necessarily situated together, that have either a common or associated function or have similar nucleotide sequences.

multigene family

a number of related or identical GENES present in the same ORGANISM that generally code for related POLYPEPTIDES. See, for example, MAJOR HISTOCOMPATIBILITY COMPLEX.
