Parameter estimates under branch-specific models among the four MEF2 branches for MADS and MEF2s coding regions.

Note: The topology and branch-specific ω ratios are presented in Figure S2. The degree of freedom (df) is 1 for the comparisons of null model H0 versus the alternative model from H1 to H6.**Significance with .注：系统发育拓扑结构与支系特异性ω比值详见图S2。针对零假设模型H0与H1至H6的备择假设模型的比较，其自由度（degree of freedom, df）均为1。显著性以（.）标注。
