Another important evolutionary force is gene flow: the flow of alleles in and out of a population due to the migration of individuals or gametes (Figure 7). While some populations are fairly stable, others experience more flux. WebMicroevolution. Microevolution changes occur due to four processes, including mutation, selection, gene flow, and genetic drift. These changes can take place over a short amount of time.
