Abstract

The principle of frequency-dependent selection, that the abundant genotypes have lower fitness and the rare genotypes have higher fitness when their frequencies deviate on either side from an equilibrium, has been justified in the present investigation by raising different proportions of the normal, Curly and Xasta flies of Drosophila melanogaster in a set of four lines at population level. The experiments were continued until a state of equilibrium was attained in each of the lines under study.
