Gene Flow and Divergence under Disruptive Selection

Elizabeth Millicent, John Marion Thoday

Open publisher page 25 citations

Abstract

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.
