Nucleotide alignments of C. elegans and C. briggsae genes were analyzed by SNAP software (see Methods). Only the C. elegans member of the ortholog pair is named. pS = proportion of observed/potential synonymous substitutions; pN = proportion of observed/potential nonsynonymous substitutions. NA – not applicable (cannot be calculated when pS > 0.75). *Includes all pairwise comparisons (n = 5) except C.e. vs. C.b. bas-1. Values are mean ± SD (strict statistical comparison with other values is not intended, as KA/KS values are not distributed normally).
