  1. 2*(lnM7-lnM8) and 2*(lnM8A-lnM8) are twice the difference of log likelihood between two models that was compared with the χ2-distribution with the given degree of freedom. The exact P-values and degree of freedom are shown (bold if <0.05). The p1 is the proportion of positively selected sites with ω1, calculated applying the M8 model.
