WebNatural Selection on Single-Gene Traits Natural selection for a single-gene trait can lead to changes in allele frequencies and then to evolution. For example, a mutation in one gene that determines body color in lizards can affect their lifespan. So if the normal color for lizards is brown, a mutation may produce red and black forms.
