aParameter id numbers in the parenthesis mean ML parameters in each model and other parameters except for Inline graphic and Inline graphic are fixed to the value of the corresponding parameter listed in the column of the ML-91 or the ML-200 in Table 3; each id number corresponds to the parameter id number listed in Table 3.

b Inline graphic #parameters with Inline graphic for JTT, Inline graphic for WAG, Inline graphic for LG, Inline graphic for cpREV, and Inline graphic for mtREV; see text for details.

c Inline graphic Inline graphic for the KHG-derived amino acid substitution probability matrix, and Inline graphic for the KHG codon substitution probability matrix; see text for details.
