WebOld populations have more neutral alleles than new populations when N e is equal. ... 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. We will call u the forward mutation ... WebEffects of mutation. A mutation may be neutral. and have no effect.

Factors in the environment may influence the rate of mutation but are not generally thought to influence the direction of mutation. For example, exposure to harmful chemicals may increase the mutation rate, but will fnko stock predictions
