Evolution 60:292-302. 2006..Although natural selection is usually thought of as accentuating divergence between species, our results imply that it can also act as a homogenizing force... - X chromosomes and autosomes evolve at similar rates in Drosophila: no evidence for faster-X protein evolutionKevin Thornton
Department of Molecular Biology and Genetics, Cornell University, Ithaca, New York 14853, USA
Genome Res 16:498-504. 2006..The lack of a detectable faster-X effect in these species suggests either that beneficial amino acids are not partially recessive on average, or that adaptive evolution does not often use newly arising amino acid mutations... - Multilocus patterns of nucleotide variability and the demographic and selection history of Drosophila melanogaster populationsPenelope R Haddrill
