Parallel faster-X evolution of gene expression and protein sequences in Drosophila: beyond differences in expression properties and protein interactions.

To confirm that these trends are representative of whole genome patterns, I also analyzed a larger set of 13,659 genes sequenced in both species (2,335 X-linked and 11,424 autosomal; see Materials and Methods for details), which produced the same non-significant results for d N (median d N = 0.0039 for X-linked genes and 0.0038 for autosomal genes; Mann-Whitney U test, P = 0.76) and marginally significant results for ω (median ω = 0.092 for X-linked genes and 0.086 for autosomal genes; Mann-Whitney U test, P = 0.026).
