WebGene Flow. Another important evolutionary force is gene flow, or the flow of alleles in and out of a population resulting from the migration of individuals or gametes (Figure 11.9).While some populations are fairly stable, others experience more flux. Many plants, for example, send their seeds far and wide, by wind or in the guts of animals; these seeds may … WebThese modification of alleles is caused by evolutionary factors such as genetic drift and natural selection (Openstax, 2024). While natural selection guides the non-random disruptive process of evolution, genetic drift is the random variation in allele frequency that causes a population's gene pool to gradually skew.
