Proportions of genes with evidence of recombination among individual JCVI role categories. Genes with evidence for recombination (Q < 0.1) in at least one of the four tests were included. Bars indicate estimated standard error for the proportion of genes with evidence of recombination in each role category; standard errors were calculated as square root of p (1-p)/n, where p is the proportion of genes with evidence of positive selection in a given role category, and n is the total number of genes in a given role category. Among the 20 JCVI role categories, two did not include genes with evidence of recombination (i.e., "Signal Transduction" and "Viral functions") and are thus not included in this figure.
