Fig. 6: Evolution of sex-biased body- and gonad-expressed genes in Bradysia coprophila and Lycoriella ingenua.
From: Faster adaptation but slower divergence of X chromosomes under paternal genome elimination
Genes are designated as body- or gonad-expressed if they are predominantly expressed in one tissue (i.e., > 50% of a gene’s expression). Note that we excluded germline (testes and ovaries) from reproductive tissues as germline and somatic karyotypes differ (see methods). a Scaled rates of divergence (dN/dS); (b) scaled rates of polymorphism (pN/pS) for autosomal (grey) and X-linked (blue) genes. MB = male-biased, UB = unbiased, FB = female-biased. Asterisks represent significance levels for two-sided Mann-Whitney-Wilcoxon tests between the X and autosomes (*P < 0.05, **P < 0.01, ***P < 0.001, NS = not significant). Box plots show median (central line), IQR (25th and 75th percentiles, box limits); whiskers extend to 1.5 x IQR. Outliers not shown. See Supplementary Table 4 for full statistical test results, including numbers of genes in each comparison.
