Fig. 6: Genes under positive selection in C. hominivorax and their developmental expression.

a Forty genes with evidence of positive selection. Dot size indicates dN/dS ratio. The larger the dot, the higher the positive selection onto the protein (averaged over all codons). The color indicates the level of significance in the comparison of the two-ratio model with the null hypothesis of neutral evolution; it shows that the null hypothesis of neutral evolution was rejected for these genes. Adjusted p-values are log transformed. 0, indicates a P value of 0, which cannot be plotted on a log scale. b Expression profiles of the genes evolving under positive selection in six developmental stages, based on Supplementary Data 8. Each expression value represents the average of three biological replicates for each stage. Blocks are based upon similarity in expression among developmental stages.
