WebFeb 19, 2024 · Gene flow, the movement of alleles across the range of the species, is relatively free because individuals can move and then mate with individuals in their new location. Thus, the frequency of an allele at one end of the range will be similar to the frequency of the allele at the other end. WebWhen there is no longer a genetic flow between members of a formerly single species, reproductive isolation has been fulfilled. They no longer share the same gene pool. When this occurs, speciation is complete, and the one species has now become two (or more). But how does speciation take place? Evolutionists still don't have a definitive answer.
