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: -The introduction of new alleles through gene flow increases variability within the population and makes possible new combinations of traits. In humans gene flow usually comes about through the actual migration of human populations, either voluntary or forced.

Detailed explanation-3: -Gene flow is also called gene migration. Gene flow is the transfer of genetic material from one population to another. Gene flow can take place between two populations of the same species through migration, and is mediated by reproduction and vertical gene transfer from parent to offspring.

Detailed explanation-4: -Gene flow within a population can increase the genetic variation of the population, whereas gene flow between genetically distant populations can reduce the genetic difference between the populations.

Detailed explanation-5: -Gene flow is the movement of genes from one population to another population. Examples of this include a bee carrying pollen from one flower population to another, or a caribou from one herd mating with members of another herd.
