WebSep 4, 2024 · There are four such forces: mutation, gene flow, genetic drift, and natural selection. Genetic Drift. Genetic drift is a random change in allele frequencies that occurs in a small population. When a small number of parents produce just a few offspring, allele frequencies in the offspring may differ, just by chance, from allele frequencies in ...
