Example of a gene flow
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 … WebReproductive isolation mechanisms prevent gene flow between different species and limit the development of hybrids, the offspring of two different species. One reproductive isolation mechanism may not completely block gene flow, but a combination can effectively separate the gene pool of a species. There are various types of reproductive ...

Gene flow is also called gene migration. Gene flow is the transfer of genetic material from one population to another. Gene flow can take place between two populations of the same species through migration, and is mediated by reproduction and vertical gene transfer from parent to offspring.
