Assume that we have two alleles at a single locus, call them A 1 and A 2, where A 1 can mutate to become A 2, and A 2 can undergo the reverse mutation to become A 1. Let A 1 mutate to A 2 at a frequency of u per generation. china stock holiday 2022WebHow can natural selection on mouse color be measured?
