Proportion of sites under diversifying selection in each gene in the CPXV genome . Black: Genes with sites under diversifying selection (Genes for which the alternative model, allowing positively sites with ω > 1, fits the data better than the null model (p < 0.05)). White: Genes without sites under diversifying selection. A) Proportions determined using model M2a and LRT against M1a. B) Proportions determined using model M8 and LRT against M7.
