Mating system manipulation and the evolution of sex-biased gene expression in Drosophila
Abstract
Sexual selection on males is thought to favour male-biased gene expression. Here, Veltsos et al. experimentally evolve Drosophila pseudoobscura under different mating systems and, contrary to expectation, most often find masculinization of the transcriptome under monogamy rather than under elevated polyandry.
