Gene flow has to do with the migration of organisms. WebGene flow is the migration of individuals between two populations of the same species. As long as individuals can move between the two populations, the populations remain as the same species because they are sharing genetic information - any new alleles (therefore traits) are passed between populations and they evolve together. ...
