Case gene flow. Medical search. Frequent questions

If the rate of gene flow is high enough, then two populations will have equivalent allele frequencies and therefore can be considered a single effective population. (wikipedia.org)
Gene flow is an important mechanism for transferring genetic diversity among populations. (wikipedia.org)
Migrants change the distribution of genetic diversity among populations, by modifying allele frequencies (the proportion of members carrying a particular variant of a gene). (wikipedia.org)
There are a number of factors that affect the rate of gene flow between different populations. (wikipedia.org)
Gene flow is expected to be lower in species that have low dispersal or mobility, that occur in fragmented habitats, where there is long distances between populations, and when there are small population sizes. (wikipedia.org)
For example, many island populations have low rates of gene flow due to geographic isolation and small population sizes. (wikipedia.org)
The level of gene flow among populations can be estimated by observing the dispersal of individuals and recording their reproductive success. (wikipedia.org)
The more genetically differentiated two populations are, the lower the estimate of gene flow, because gene flow has a homogenizing effect. (wikipedia.org)
When gene flow is blocked by physical barriers, this results in Allopatric speciation or a geographical isolation that does not allow populations of the same species to exchange genetic material. (wikipedia.org)
In some cases, they can be artificial, man-made barriers, such as the Great Wall of China, which has hindered the gene flow of native plant populations. (wikipedia.org)
