An experiment on recombination load in Drosophila melanogaster

Abstract

This paper describes the results of an experiment to measure the effect on mean population fitness of recombination in the second chromosome of Drosophila melanogaster. There was a small and non-significant effect of recombination in lowering egg-to-adult viability of heterozygotes for wild-type chromosomes. A large (7%) and significant effect of recombinant chromosomes on the fecundity of Cy female carriers was detected. © 1975, Cambridge University Press. All rights reserved.
