Description

Gene flow is the transfer of genetic material from one population to another. Such movements can result from the movements of individual organisms breeding in new populations, or the movements of gametes. There are many factors that affect the rate of gene flow between different populations. Gene flow is expected to be lower in species with low dispersal or mobility that occur in fragmented habitats with large population distances, and in species with small populations. Mobility plays an important role in penetration, as highly mobile individuals tend to be more likely to move. Animals are considered to be more mobile than plants, but pollen and seeds can be carried over long distances by animals, water, or wind. Interfering gene flow can increase the coefficient of inbreeding, as measured by the coefficient of inbreeding within the population.

Measuring gene flow provides indirect information about the degree of migration between subpopulations. However, this information is of equal value, depending on the issue of either "lack of gene flow" or "complete gene flow." The lack of gene flow is useful information, as immigration is very unlikely to occur in these situations (genetic divergence). Ineffective information is for complete gene flow, as no one can confirm that such (non-existent) gene structures reflect current levels of migration. Gene flow does not change the allelic frequency of the entire species, but it can change the allelic frequency of the local population. In the case of migrants, the greater the difference in allele frequency between resident and migrants, and the greater the number of migrants, the greater the impact of migrants on changes in the genetic composition of the resident population.

Gene flow and subdivided populations

Gene flow includes not only the spread of individuals throughout the universe, but also the successful reproduction of individuals in new locations. The local mating system of the individual to which the individual moves can affect the reproductive potential of the new individual and thus the amount and pattern of gene flow. In particular, mating systems that prefer assortative mating (inbreeding) or inbreeding tend to reduce gene flow, while avoidance of disassortative or inbreeding tends to increase gene flow.

Gene flow and evolution of new weeds and invaders

No need to develop new weeds or invading plants includes everything tamed. Natural gene flow, including only nondomestic taxa, and subsequent mixing they are known to have preceded the development of dozens of new things. Weeds and invasive species. Examples include plants, animals and microbes. There is more and more research these days showed that even the mixture appears to be in the species it has played a role in the development of many invasion lines. In this case, the mixture depends on some referrals

Gene flow and conservation

The rise of conservation genetics in the 1980s began with a focus on fragmentations and small populations showing the risks associated with drift, inbreeding, and lack of variability in the face of environmental problems. Early on, gene flow was widely seen as a benefit to endangered populations as a means of reversing those risks.

Gene flow and policy

Gene flow is currently the subject of research across fields and laboratories. If necessary, the decision maker will include information and questions related to gene flow in policy.

Gene flow consists of different types, they are

Vertical gene transmission: It can occur between two populations of the same species, from parent to offspring. Genetics are transmitted from parents to children by horizontal gene transfer. It can be either sexual or asexual. Horizontal gene transfer, on the other hand, is the transmission of genetic material from a donor organism to an organism that is not its offspring.

Horizontal Gene Transfer (HGT): It is the transmission of genetic information between organisms, the process by which antibiotic resistance genes spread between bacteria (excluding parent-to-progeny antibiotic resistance genes) and promote the development of pathogens. The majority of HGT include the presence of genes from bacteria in the nucleus. Their popularity maybe because they are more visible than genes from other eukaryotes, yet bacteria may be the primary source of new genes due to their number.
