The questions below are just a few. A pair of alleles show heterozygote advantage in their fitnesses. A. Mutation tends to produce adaptive alleles as needed. B. Mutation is a significant force in changing gene frequencies. C. Mutation pressure can maintain the existence of an allele against selection.
All mutations have an effect on the phenotype.
In a population of 35,600 individuals a new neutral mutation arises. At a given time, a population has an average heterozygosity of 0.65 at a locus. The population size is 100 individuals. This one might take a bit of thought, since it asks for a calculation we didn't go over specifically. But it's not hard to derive if you think it through. 5.
