‘Sum’ indicates the sum of all I D calculated for a particular taxon, and ‘Mean’ indicates the average of I D for that taxon. Taxa with high I D-values have a significantly different base compositional bias from the rest of the species. Numeric values shown next to PCG (i.e. PCG1) represent codon positions. The values shown here highlight the level of base compositional heterogeneity in our dataset.
