WebNov 4, 2024 · A second example of genetic drift is observed in what is known as the founder effect. In this instance, a small group of individuals become separated from the main population and establish a new population. Webgene flow, also called gene migration, the introduction of genetic material (by interbreeding) from one population of a species to another, thereby changing the composition of the gene pool of the receiving population. The introduction of new alleles through gene flow increases variability within the population and makes possible new combinations of traits. …
