Multiple comparisons of evolutionary rates among reproductive processes.

<p>Average synonymous (dS) and non-synonymous (dN) substitutions were calculated for different groups. <i>P</i>-values above the diagonal represent pairwise comparisons of dN rates whereas <i>P</i>-values below the diagonal show comparisons of dS rates. (*) and (**) indicate statistical significance with a 95% and 99% confidence interval respectively.
