gene flow
Gene flow, also known as migration is the movement of individuals, and/or genetic material they carry from one population to another. If gene versions are carried to a population where, those gene versions previously did not exist, gene flow can be very important source of genetic variation. Evolution can also occur as a result of genes being transferred from one population to another.
The loss or addition of species can easily change the gene pool frequencies. Plants experience gene flow by spreading their pollen long distances by wind, insects, or birds to pollinate other populations of the same species. Animals experience gene flow when individuals lave a family group to join other populations. The flow of individuals in and out of a population introduces new alleles and increases genetic variation within that population. An important evolutionary force is gene flow. It is the flow of alleles in an out of a population or gametes. The variable of individuals in and out of the group not only changes the gene structure of the population, but can also introduce new genetic variation to populations in different geological locations and habitats
