Experimental test of the conditions of maintenance of polymorphism under hard and soft selection
Theoretical work, initiated by Levene (1953)  and Dempster (1955) , suggests that within a given environment, the way populations are regulated and contribute to the next generation is a key factor for the maintenance of local adaptation polymorphism. In this theoretical context, hard selection describes the situation where the genetic composition of each population affects its contribution to the next generation whereas soft selection describes the case where the contribution of...
