WebFor example, say that a population has an allele frequency of p = 0.25, and it receives immigrants at a rate m = 0.1 from another population whose allele frequency is 0.75. The equation Δ p = m (p m - p ), tells us that the change in allele frequency is 0.05, so migration will cause the allele frequency in the focal population to increase from p = 0.25 to 0.3.
