Gene Flow and Genetic Drift are defined as follows: Identifying the distinction between Gene Flow and Genetic Drift For example, an animal or plant from a different gene pool (originating from a different geographic location) may be introduced to a small population in order to improve its fitness. When humans assist gene flow, they are assisting animals that are endangered by extinction and have low genetic quality as a result of inbreeding rates that are extremely high. The phenomenon of inbreeding occurs when there is a restriction of movement, as is true in the instance of the Black Footed Rock Wallaby, which is restricted to a small number of Australian islands. Gene migration is frequently lower in species that are not very mobile, that are located in isolated places, and that have limited population sizes, among other factors. So, for example, when people from villages B and C have children with those from village A, the genetic composition of the offspring from village A becomes more diverse than it was before. This mechanism is critical in the creation of genetic diversity within a genetic pool. It is defined as the transfer of genetic variation from one group to another through natural selection. Gene flow is sometimes referred to as gene migration or allele movement in other contexts. The discussions that follow will go into greater depth about these discrepancies. Genetic drift, on the other hand, is concerned with the shift in allele frequencies that occurs as a result of random sampling from one generation to the next. ![]() ![]() In terms of their contrasts, gene flow is especially concerned with the migration of populations, whereas genetic variation is concerned with the alteration induced by the introduction or elimination of an allele.
