  1. Where each entry shows the probability of substitution (r) from one base (row) to another base (column). Rates of different transitional substitutions are shown in bold and those of transversionsal substitutions are shown in italics. Against the nucleotide frequencies are 33.95% (A), 33.82% (T/U), 16.12% (C), and 16.11% (G). The transition/transversion rate ratios are K1 = 2.573 (purines), K2 = 2.282 (pyrimidines), and the overall transition/transversion bias is R = 1.06 with a total of 7110 positions in the final dataset
