Using Average Relative Fitness (W¯) for Intergroup Comparisons: A Caution

B. Wallace

Department of Biology, Virginia Polytechnic Institute and State University Blacksburg, VA 24061

Abstract

The average relative fitnesses (Formulas) of different populations are used at times for mterpopulation comparisons of fitness. Such comparisons should be made with extreme caution. The data presented here show that the Formulas of several populations of Drosophila melanogaster, comparable in their calculated values, did not reveal a 12-fold difference between populations with respect to one component of fitness, the mating success of male flies.
