Maximum-likelihood phylogeny of the 67-taxon TGFB2 data set. This data set was composed of up to 1078 bp. Among the ingroup, 58 characters were parsimony-informative. Estimated ML model parameters conform to the GTR+G model of sequence evolution. -ln L = 3186.405935, rate matrix: A-C = 0.883433, A-G = 2.425602, A-T = 0.769195, C-G = 0.592286, C-T = 1.898448, G-T = 1. Base frequencies: A = 0.29, C = 0.21, G = 0.20, and T = 0.30, and γ-shape parameter = 0.862394. Thick branches indicate nodes with ≥ .95 BPP and ML and MP bootstrap values ≥ 70.
