- Genes that are not single-copy or have a high level of divergence (i.e., d
S
> 1) are excluded because the substitution rate estimates are not reliable. Level 6 genes are not included because they are species-specific and have no orthologous sequence for comparison. The nonsynonymous substitution rate (d
N
) indicates the number of nonsynonymous substitutions per nonsynonymous site; the synonymous substitution rate (d
S
) indicates the number of synonymous substitutions per synonymous site.
