  1. a Based on likelihood analyses of 5-gene, 123-taxon character sets and subsets. The single constraint tree on which parameters are optimized is derived from analysis of nt123.
  2. A, number of characters; B, average number of substitutions per character across all branches; A × B, Tree length = number of substitutions for all characters across all branches. Numbers in parentheses represent comparisons to the nt123 values, defined as 1.0.
