WebConsider again the island model: a large number of demes, each of constant size N, are connected by gene flow at a rate m via a common pool of migrants. The overall frequency of a certain selectively neutral allele in the population as a whole, and consequently in the migrant pool, is p ¯.Genetic drift within demes produces variance in p across demes as a … WebGene flow is the movement of genes into or out of a population.
