This could lead to 'faster-X evolution', if a large proportion of mutations are fixed by positive selection, as suggested by recent studies in Drosophila. We used a multispecies approach to test this: Muller's element D, an autosomal arm, is fused to the ancestral X chromosome in Drosophila pseudoobscura and its sister species, Drosophila affinis. We tested whether the same set of genes had higher rates of non-synonymous evolution when they were X-linked (in the D. pseudoobscura/D. affinis comparison) than when they were autosomal (in Drosophila melanogaster/Drosophila yakuba). Although not significant, our results suggest this may be the case, but only for genes under particularly strong positive selection/weak purifying selection. They also suggest that genes that have become X-linked have higher levels of codon bias and slower synonymous site evolution, consistent with more effective selection on codon usage at X-linked sites."}],"date_updated":"2021-01-12T06:55:05Z","intvolume":"        90","publication":"Genetical Research","date_published":"2008-10-01T00:00:00Z","quality_controlled":0,"day":"01","year":"2008","month":"10","issue":"5","title":"A multispecies approach for comparing sequence evolution of X-linked and autosomal sites in Drosophila","doi":"10.1017/S0016672308009804","_id":"2065","citation":{"apa":"Vicoso, B., Haddrill, P., &#38; Charlesworth, B.
