Question

_____ is when the heterozygote has a higher fitness than either of the two homozygotes (W₁₁ < W₁₂ > W₂₂).Allele frequencies will change in this population until _____.

Quizplus · Accepted Answer

Overdominance is when the heterozygote has higher fitness than either homozygote, and this can lead to a stable equilibrium where multiple alleles are maintained in the population. Therefore, allele frequencies will not necessarily change until new mutations or other evolutionary forces act on the population.
