What is gene flow?
The transfer of genetic material or alleles from one population within a species to another is referred to as gene flow, gene migration, or allele flow. Individuals migrate between groups, which causes this gene flow and the potential for genetic variety exchange.
Gene flow can offset the effects of natural selection or genetic drift and is essential to preserving genetic diversity within a species.
It is a significant factor in the evolution of populations, as the introduction of new genetic material can influence the overall genetic makeup of a population.
