When selective pressures differ between males and females, the genes experiencing these
conflicting evolutionary forces are said to be sexually antagonistic. Although the phenotypic …

The repeatability or predictability of evolution is a central question in evolutionary biology
and most often addressed in experimental evolution studies. Here, we infer how genetically …

Transcriptional enhancement of X-linked genes to compensate for the sex chromosome
monosomy in Drosophila males is brought about by a ribonucleoprotein assembly called …

In many taxa, males and females have unequal ratios of sex chromosomes to autosomes,
which has resulted in the invention of diverse mechanisms to equilibrate gene expression …

Genes with sex-biased expression in Drosophila are thought to underlie sexually dimorphic
phenotypes and have been shown to possess unique evolutionary properties. However, the …

Sexual dimorphism in morphological, physiological, and behavioral traits is pervasive in
animals, as is the observation of strong sexual dimorphism in genomewide patterns of gene …

Sexual selection drives faster evolution in males. The X chromosome is potentially an
important target for sexual selection, because hemizygosity in males permits accumulation …

In many taxa, males and females differ with respect to their sex chromosomes, and dosage
compensation mechanisms have evolved to equalize X-linked gene transcription. In …

Selfish genetic elements occur in all living organisms and often cause reduced fertility and
sperm competitive ability in males. In the fruit fly Drosophila pseudoobscura, the presence of …

We have sequenced the genome of a second Drosophila species, Drosophila
pseudoobscura, and compared this to the genome sequence of Drosophila melanogaster, a …
