:''For the guitarist named '''Gene Pool''', see [[Greg Flesch]].''
In [[population genetics]], a '''gene pool''' is the complete set of unique [[allele]]s in a [[species]] or [[population]]. A large gene pool indicates extensive [[genetic diversity]], which is associated with robust populations that can survive bouts of intense [[selection]]. Meanwhile, low genetic diversity (see [[inbreeding]] and [[population bottleneck]]s) can cause reduced [[fitness (biology)|biological fitness]] and an increased chance of [[extinction]].
When many alleles exist for a given gene or [[locus (genetics)|locus]], a population is said to be [[polymorphism (biology)|polymorphic]] with respect to that gene or locus. When no variation exists, it is labelled monomorphic.
