Fig. 5
Comparison of dTN and selection pressures variance across similar clades. The figures show a comparison of genetic distance and selection pressure standard deviation among multiple similar clades. We represented the standard deviation (S.D.) rather than the variance to make the figure easier to interpret, as squaring the S.D. would make the values hard to plots on the same axis. Each datapoint in the figures is computed from the S.D of each gene in the clade considered. For example, the four datapoints present in Cnidaria correspond to the S.D. of the four mt-gene analysed. Nematoda had only two genes conserved across all species, thus we excluded this phylum from the comparison. Although the datapoints are the same, the boxplots highlight the differences between clades, while the violinplot highlight the difference across clades and phyla. The numeric axis in each figure is the S.D. of either genetic distance or selection pressure, and the axes have the same values in both boxplots and violinplots.
