What is the genetics of the flow of the gene?

The flow of the gene is the transfer of alleles, various forms of gene coding for specific features, between different populations of individuals. In some cases, this may increase genetic diversity and reduce it in others depending on the circumstances. In some cases it occurs both in populations of the same species and in populations of different species. Trans-second transmission is more rare and is usually seen between bacteria that have the ability to transmit genes across species using special proteins called plasmids. Insects, animals or agricultural equipment could transmit pollen from one side to the other and introduce new alleles to the population. Purple flowers could develop multiple blue samples and vice versa. EEGENT E gene due to migration. This can be seen significantly in human populations. For example, in the United States, people with alleles from several origins emphasize the role that migrants played in the history of this country. Migration may not be permanent to have a genetic impact if passengers have enough time to reproduce with the inhabitants and leaveeating a genetic legacy behind.

Some forms of gene flow increase the biological diversity. They represent new features of the population that can increase hardness and diversity. In other cases, they can limit the natural variation. The dominant feature could quickly erase more fragile recessive, especially in a small isolated population. Over time, slightly different populations could become a more homogeneous nature without their own properties.

It may be concerned about the population of plants and animals on long -distance ipomles and in other isolated areas. They can begin to specialize and divide into populations with significant and clear differences. If genetic material is introduced from another source, these differences can be deleted and unique properties developed in this environment may be lost.

The pure effect of this phenomenon may depend on the Genets andon the population. Sometimes, for survival, critical fresh infusions of the allele of the gene flow, as can be seen in the Jewish population of Ashkenazi, where many people carry dangerous genetic features due to historically island culture. Marriage with people from other regions can reduce the risk of marriage between two carriers that could lead to a child with a genetic disorder.
