WebApr 24, 2024 · Gene flow differs from genetic drift because it is the transfer of alleles or gametes from one population to another. It happens when a population migrates or becomes geographically isolated. This is different from the genetic drift seen with the founder effect where the new group is formed in an area that does not have an existing population.

WebGene flow, which occurs when breeding between two populations transfers new alleles into a population, can also alter the Hardy-Weinberg equilibrium. WebGene flow is the process acting on and creating genetic sub-populations. The flows occur over landscapes and amongst populations that are distributed in space with varying distances of separation.

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.

WebDiscussions of gene flow started shortly after the definition of population genetics in the early 1900s, although the term itself first appeared in 1941. Its early usage was most commonly theoretical in nature because, except for breeding experiments, the inheritance of characters from parents to offspring was poorly understood: only the ...

WebGene flow is the migration of individuals between two populations of the same species.
