Figure 7.
Comparisons of gonad sex-biased and unbiased genes on autosomes and the respective sex chromosomes of the seven taxa with previously described sex chromosomes. Colours refer to sex chromosomes as shown in figure 1: green, LG5/LG19; orange, LG11/LG15; and purple, LG19. (a) Fractions of FBGs, MBGs and unbiased genes. Symbols of individual datapoints refer to species as depicted in the inlet. (b) Intersex Fst of FBGs, MBGs and unbiased genes. (c) π of FBGs, MBGs and unbiased genes. (d) Tajima's D of FBGS, MBGs and unbiased genes. (e) dN/dS of FBGs, MBGs and unbiased genes. Species values in (b)–(e) are plotted in the order shown in the inlet. Boxplot centre lines represent the median, box limits the upper and lower quartiles and whiskers the 1.5× interquartile range. Significance levels of a Wilcoxon test comparing for each expression category autosomes and sex chromosomes are indicated with *p ≤ 0.05, **p ≤ 0.01, ***p ≤ 0.001, ****p ≤ 0.0001. Outliers are not shown for (b–e); not significant p-values are not shown.
