The migration of breeding individuals between populations causes a corresponding movement of alleles, which is referred to as:

A) mutation.
B) gene flow.
C) genetic drift.
D) natural selection.
E) directional selection.

Gene Flow

Gene flow is the transfer of genetic variation from one population to another, which can influence the genetic structure of the receiving population.

Breeding Individuals

Refers to the selection of specific animals or plants for reproduction, aimed at enhancing desirable traits.

Alleles

Different versions of a gene that exist at the same locus on homologous chromosomes, contributing to genetic variation.
