Under standard inheritance, autosomal genes can be constrained in responding to divergent selection between the sexes.  Using Drosophila melanogaster, we used an experimental manipulation to evolve populations in which ~50% of the autosomal genome was largely released from the constraints imposed by being part of a gene pool equally shared across the sexes. Instead, the experimental manipulation resulted in two gene pools: one that experienced selection only through males and the other that experienced selection primarily through females. Here we examine divergence between these gene pools with respect to genetic properties putatively believed to be related to sexual dimorphism and sexual conflict.
