Population Genetics II Mutation – selection balance

In the absence of heterozygote advantage or disadvantage (i.e. with 0 ≤ h ≤ 1), when selection alone would eliminate the deleterious allele, mutation will offset this effect and lead to an equilibrium at which the deleterious allele will persist. (This equilibrium will be stable, though this won’t b ...
