  1. Mean, standard-error (SE), minimum (MIN) and maximum (MAX) values are given for exon length, variability (% of variable sites on the complete alignment), relative variability (% var) among codon positions (% of the variable sites that respectively occurred on first [1st], second [2nd], and third [3rd] codon positions), substitution rate heterogeneity among sites (α), Guanosine + Cytosine content on all (GC) and third (GC3) codon positions, relative composition variability (RCV), relative GTR substitution rates (A-C to G-T), average transition/transversion rate ratio (Ti/Tv), total branch length (TBL) of the tree, and relative evolutionary rate (as measured by the SDM procedure).
