Heterogeneity in dN/dS ratios over sites.
| Fraction of codons | Branchlength | ||||||||
| Model | ω = 0 | ω = 1/3 | ω = 2/3 | ω = 1 | ω = 3 | Pig | Mouse | Human | Kappa |
| CT | 0.691 | 0.238 | 0.055 | 8 × 10-5 | 0.016 | 0.221 | 0.418 | 0.163 | 2.494 |
| F3 × 4 | 0.681 | 0.245 | 0.058 | 1 × 10-5 | 0.017 | 0.219 | 0.410 | 0.162 | 2.658 |
The concatenated super gene is used to estimate the distribution of dN/dS ratios over sites. Each codon is allowed to fall into one of the five predefined dN/dS ratio classes. The branch lengths are expressed as number of substitutions per codon.
