  1. 1 Uncorrected pairwise sequence divergence.
  2. 2 Ratio of transitions to transversions.
  3. 3 Protein coding genes: synonymous substitutions vs. non-synonymous.
  4. 4 Ribosomal genes: the number of distinct haplotypes that differed for indels (insertion/deletion).
  5. 5 Average length in base pairs of indels.
