process of genes moving from one population to another
gene flow
The process of genes moving from one population to another is called gene flow, also known as migration. This occurs when individuals from one population migrate and mate with individuals from another population. This can happen through a variety of means including animals physically moving between populations, plants dispersing their seeds via wind or animals, or humans transporting organisms intentionally or unintentionally.
Gene flow can have a significant impact on the genetic diversity of a population. When genes from one population are introduced to another, it can lead to new combinations of alleles which can increase genetic variation within a population. If the gene flow is continuous, the genetic makeup of the two populations can become more similar over time. In contrast, if the gene flow is sporadic, certain alleles may be introduced into a population and then lost due to insufficient time to become established.
Gene flow can also have important implications for evolution. When new alleles are introduced to a population, they may be subject to natural selection, which may result in the evolution of a new trait. For example, if an allele for resistance to a particular disease is introduced into a population, it may spread quickly if it provides a selective advantage. Over time, this can lead to the evolution of a population that is more resistant to the disease.
Overall, gene flow is an important phenomenon that helps to shape the genetic diversity of populations and can play a critical role in evolution.
