Effective gene flow plays an important role in maintaining genetic diversity … WebGene flow is the migration of individuals between two populations of the same species. As long as individuals can move between the two populations, the populations remain as the same species because they are sharing genetic information - any new alleles (therefore traits) are passed between populations and they evolve together. ...

Web2.3.3 Gene Flow and Introduction of Genetic Diversity. 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. WebGene Flow definition. Gene flow refers to the movement (in and out) of genes and alleles caused by the migration of organisms, or their gametes, between populations. Although …
