  1. a Three phylogenetically uninformative loci removed from original data set of 254 loci b PhyLoTA database [52]
  2. Values in parentheses correspond to the reference subset of taxa. Fraction of triples is the fraction of all possible triples of taxa that are present for at least some locus (column) of the taxon coverage pattern. ∏ D is the probability the taxon coverage is decisive for the reference subset on a random binary tree. ∏ d is the average number of edges distinguishable on a random binary tree (see text for further details).
