Distributions of ω C -ω A , ω C -ω AN , ω C -ω AI , ω C -ω AC . a. The distribution of ωC-ωA for 2358 genes with the total length of human-mouse alignments of constitutive regions and of alternative regions both exceeding 80 bp shows that ω tends to be larger in alternative regions. In particular, there are 23 genes with ωC-ωA<-0.8 and no genes with ωC-ωA>0.8. b, c, d. The distributions of ωC-ωAN, ωC-ωAI, ωC-ωAC for genes with long N-terminal (1674 genes, top, ωC-ωAN), internal (976 genes, middle, ωC-ωAI), and C-terminal (110 genes, bottom, ωC-ωAC) alternative regions, respectively, show that ωA* tends to be larger than ωc in all types of alternative regions. the grey shadows are symmetrical to the left parts of the histograms.
