...to Muller element F in Drosophila melanogaster (the ancestral fly X Chromosome; 55.6% of fly Muller F genes, chi-squared test, 1 d.f., P = 3.84 × 10−31) (Vicoso and Bachtrog 2013) despite 400 million years of divergence. Through
functional enrichment analysis, we show that these conserved X-linked genes...
