Phylogenetic informativeness. Profile of (A) net and (B) per site phylogenetic informativeness for selected regions within rDNA. The time axis was calibrated to the ultrametrisized ML tree calculated for the complete rDNA unit. An evolutionary time of 1.0 corresponds to the root of the tree and the value of 0 to its tips.
