WebApr 9, 2024 · Genetic drift stems from the chance occurrence that some individuals in the germ line have more offspring than others. When individuals leave or join the population, allele frequencies can change as a result of gene flow. Mutations to an individual’s DNA may introduce new variation into a population. WebGenetic drift is a change in the gene pool of a small population due to chance and results from a drastic reduction in population size.
