Detailed explanation-1: -Gene flow is the movement of genes into or out of a population. Such movement may be due to migration of individual organisms that reproduce in their new populations, or to the movement of gametes (e.g., as a consequence of pollen transfer among plants).

Detailed explanation-2: -Gene flow is the process by which certain alleles (genes) move from one population to another geographically separated population.

Detailed explanation-3: -Gene flow-also called migration-is any movement of individuals, and/or the genetic material they carry, from one population to another.

Detailed explanation-4: -Gene flow is a term that describes mechanisms of gene transfer from one population to another. In anthropology, gene flow more generally refers to allelic change due to movement of individuals from one place to another.

Detailed explanation-5: -What causes gene flow? The migration of individuals from one population to another and the movement of gametes cause gene flow.
