Mutation–Selection BalanceLive
evolution of an allele
Controls
Presets
Selection pushes a favorable allele toward fixation, while mutation keeps feeding the alternative back in. The two forces settle at a mutation–selection balance — which is why harmful alleles never fully disappear from a population. Educational tool.
