Detailed explanation-1: -Gene flow involves the movement of genes into or out of a population, due to either the movement of individual organisms or their gametes (eggs and sperm, e.g., through pollen dispersal by a plant).
Detailed explanation-2: -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-3: -Gene Flow. Another important evolutionary force is gene flow, or the flow of alleles in and out of a population resulting from the migration of individuals (Figure 5).
Detailed explanation-4: -Gene flow is a fundamental agent of evolution based on the dispersal of genes between populations of a species. It involves the active or passive movement of individual plants, animals, gametes, or seeds.
Detailed explanation-5: -There are four key mechanisms that allow a population, a group of interacting organisms of a single species, to exhibit a change in allele frequency from one generation to the next. These are evolution by: mutation, genetic drift, natural selection, and gene flow.
