a, Karyoplots for five dioicous species showing the following features from bottom to top: chromosome compartments (autosomes, PARs and SDR), relative gene ages, interspecies Ks values, and proportion of coding (CDS, red) and repeat (TEs, blue) density. Statistically significant differences for each feature between each autosome and the V chromosome are depicted on top of the track for that autosome (FDR-corrected two-sided Wilcoxon rank-sum test; values indicated with solid colours when P < 0.01 for the tested hypothesis). The precise range of gene age categories and interspecies Ks values for each species can be found in Supplementary Figs. 7–11. b, Violin plots for five dioicous species showing the relative gene age ranks (higher ranks equate to younger ages) of the TRGs across chromosome compartments (autosomes, PARs and SDR). Statistically significant differences in mean values of gene ages (centre line) were assessed using FDR-corrected two-sided permutation tests.
