Gene Families: Formation and Evolution

Abstract

A gene family is a set of genes derived by duplication of an ancestral gene. Various gene families, from small to large and from uniform to diverse, reflect effects of natural selection, random genetic drift and molecular mechanisms of gene duplication.

Keywords: evolution of new function; gene duplication; genetic regulatory system; genomic complexity; drift; selection
