Gene Flow and Divergence under Disruptive Selection

Gene Flow and Divergence under Disruptive Selection

Two halves of a population exposed to selection in opposing directions can diverge despite gene flow of the same amount as is given by random mating. Divergence was as great as it is with complete isolation. Isolation, therefore, is not a prerequisite of divergence under divergent selection pressure...

Zusammenfassung:Two halves of a population exposed to selection in opposing directions can diverge despite gene flow of the same amount as is given by random mating. Divergence was as great as it is with complete isolation. Isolation, therefore, is not a prerequisite of divergence under divergent selection pressures.
