Codon model selection based on modified Bayesian Information Criterion (mBIC) of AKT3 genes.

Classes	Models	Credible	mBIC	ΔmBIC	dN/dS (rates in class)
1	1	0	27660.8		0.08/75
2	7399	2505	27550.7	110.08	0.04/50		0.17/25
3	845	0	27566.0	-15.26	0.03/21	0.06/29	0.17/25

: number of rate classes included in models; Models: genetic algorithm models; Credible: all the models evaluated by genetic algorithm within 9.21 mBIC unit (the best model has credible values 0.01 or >1); mBIC: modified Bayesian Information Criterion; ΔmBIC: mBIC for rate classes compared to rate classes; dN/dS: maximum likelihood estimates for each rate class.
