Fig. 3: Rates of divergence between species pairs within the PGE families Sciaridae and Cecidomyiidae and the non-PGE family Bibionidae.
From: Faster adaptation but slower divergence of X chromosomes under paternal genome elimination
a BUSCO-based phylogenetic tree showing all species analysed (see Supplementary Fig. 1 for separate X and autosome trees). Values at branches represent branch length; bold values at nodes represent ultrafast bootstrap support (%). b Comparisons of dN/dS for autosomal (grey) and X-linked (blue) genes between each species pair (outliers not shown). For a version with medians emphasised, see Supplementary Fig. 2. Numbers on x-axes show the number of autosomal and X-linked genes single-copy orthologs tested. Asterisks represent significance levels for two-sided Mann-Whitney-Wilcoxon tests between the X and autosomes (**P < 0.01, ***P < 0.001; see Supplementary Table 1 for full statistical results). Box plots show median (central line), IQR (25th and 75th percentiles, box limits); whiskers extend to 1.5 x IQR. Outliers not shown.
