: Recombination-driven delay leads to over-dispersion of evolutionary rates within taxa and negatively correlates with gene turnover rate. a The divergence of individual genes (black lines) grows linearly after the establishment of barriers to gene conversion, whereas the overall divergence (blue lines) grows non-linearly as the barriers spread across the genome. The mean (blue arrows) and standard deviation (black arrows) of the gene-specific divergences are determined by the values of the recombination-driven delay (τ∞) and the tree depth (Dtree). b Standard deviations of the relative evolutionary rates (corrected by gene-wise and taxon-wise rates) as a function of the recombination-driven delay (left). Each data point corresponds to one of the taxa from Fig. 3. Correlation coefficient R = 0.64 (Pearson, p < 0.001, n = 34). On the right, boxplots of the standard deviation of relative evolutionary rates in linearly diverging (τ∞ > Dtree) and strongly delayed taxa (τ∞ « Dtree); center line, median; box limits, upper and lower quartiles; whiskers, 1.5× interquartile range; **statistically significant with p = 0.002 (two-tailed Student’s T test, 32 d.f.). c Negative association between the recombination-driven delays and the relative rates of gene turnover with respect to substitutions; Spearman’s correlation coefficient rho = −0.86 (Spearman’s rank-order correlation p < 0.001, n = 34).
