=== Gene frequency ===

In modern scientific use, it is often defined as a '''change in gene frequency'''.  

In modern scientific use, it is often defined as a '''change in [[gene frequency]]'''.

That is, a change in the prevalance of a given variation ([[allele]]) of a [[gene]] in a population compared to other variations of that gene.

E.O. Wilson defines evolution as "any change in [[gene frequency]] in a population."  Helena Curtis and N. Sue Barnes define evolution as "any change in the frequency of [[allele]]s within a [[gene pool]] from one generation to the next"<ref Name="TO" />
