Gene flow occurs when individuals move into or out of a population. If the rate of migration is high, this can have a significant effect on allele frequencies. The allele frequencies of both the population they leave and the population they enter may change.

WebMay 3, 2024 · Referencing the specific context of transferring genetic variation between populations, gene flow is often used interchangeably with migration, although migration also includes population movement into unoccupied regions, which according to some sources is not considered gene flow. WebIn practice, the terms migration and gene flow are equivalent in population genetics, although in other fields, such as ecology, migration may mean instead seasonal migration. This article treats gene flow and migration, as used in population genetics, equivalently.

WebEvolution by gene flow (migration) makes two different populations more similar to each other Two different populations are often subject to different selective pressures and genetic drift, so they would be expected to have different allele frequencies. WebGenetic drift is a mechanism of evolution in which allele frequencies of a population change over generations due to chance (sampling error). Genetic drift occurs in all populations of non-infinite size, but its effects are strongest in small populations.
