  1. *RCVE: relative contribution to the variability explained (see Materials and methods for more details). †Cis: divergence of cis-regulatory sequences in 2 kb surrounding TSS (see Materials and methods for more details). ‡NS: not significant after Bonferroni correction for multiple tests. §TSS: shared versus not shared TSSs. ¶Tandem: tandem versus nontandem organization of duplicate genes. ¥Structure: structural heterogeneity in coding sequences. #ω:K A /K S ratio.
