Gene flow is genes moving between two populations.
Gene flow refers to all the mechanisms that generate movement of genes from one population to another.
The populations of a species can exchange genes to a greater or lesser degree, either by nuclear genes or uniparental genomes, as well as by extinction and recolonization events of entire populations.
Gene flow conceives migrant populations that carry different alleles (or different frequencies of the same alleles), which can change the gene and genotypic frequencies of the recipient population.
The study of gene flow is vital in evolutionary biology, since it is an important component in the structure of populations, being a determining factor in the generation of biological diversity of populations.
Therefore, we can conclude that gene flow is genes moving between two populations.
