Detailed explanation-1: -In population genetics, gene flow (also known as gene migration) is the transfer of alleles or genes from one population to another. Migration into or out of a population may be responsible for a marked change in allele frequencies (the proportion of members carrying a particular variant of a gene).

Detailed explanation-2: -gene flow, also called gene migration, the introduction of genetic material (by interbreeding) from one population of a species to another, thereby changing the composition of the gene pool of the receiving population.

Detailed explanation-3: -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-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.
