Fig. 3

Distributions of correlation coefficients from COEVOL. Only results from chains that converged are displayed. A negative correlation coefficient indicates a relationship between global recombination rate and purifying selection for a gene while a positive correlation indicates a relationship between recombination rate and relaxed selection for a gene. The total distribution is displayed in grey, while the significant distribution for posterior probabilities of 0.025 and 0.975 are shown in red, and corrected posterior probabilities for 5 % significant results are in blue
