  1. Note: θI and θII, the coefficients of Type-I and Type-II functional divergence between two gene clusters; LRT, Likelihood Ratio Statistic, for p < 0.05 was marked by *p < 0.01 was marked by **Qk, posterior probability. Large Qk value indicates a high possibility that the functional constraint (or the evolutionary rate) or the physicochemical properties of a given amino acid site is different between two clusters.
