Synonymous and non-synonymous substitution rates. Violin plots describing the distribution of dN, dS, and dN/dS values calculated on sex-biased genes (a), sex-biased genes with a log2 FC > 3 (b), and sex-biased genes conserved in the six species analysed in this study (c). Asterisks indicate statistical significance between groups (pairwise Wilcoxon’s rank-sum test: ***p-value < 0.001; **p-value < 0.01; *p-value < 0.05). The black point indicates the median value
