Answer:
The phenomenon know as gene flow introduces new alleles into a population, which promotes genetic variety.
Explanation:
In genetics, the concept of gene flow is related to the interaction of different populations of the same species. The gene flow model is based on the ability of a population to transfer alleles to another population, which promotes genetic variety.
One of the determinants of gene flow is the mobilization of individuals within a population, called migration. To the extent that a population is no longer isolated and begins to move, gene flow will increase and so will genetic variety.
