WebbThe general time reversible model with discrete gamma distribution, including invariable site (GTR + I + G, nst = 6 gamma categories) (Tavaré, 1986) was recommended for the COI data; a codon nucleotide model (i.e. Nucmodel = Codon) was implemented for all COI data using metazoan mitochondrial translation (i.e. Code = metmt).

WebbFirst, SSR rate parameters are not comparable across data sets, unlike the proportion of invariable sites or the alpha shape parameter of the gamma distribution. Second, the extreme among- site rate variation within codon positions is problematic for SSR models, which explicitly assume rate homogeneity within each rate class.

WebbOne attempt to take this acknowledged biological fact into account is to suppose that a proportion of sites are invariant while others evolve at the same single rate. PHASE provides this invariant model. One extra parameter in the model governs the proportion of sites with zero rate of evolution.
