Table of the summary of systematic analysis of positive selection. Analysis included all usable clades of Caenorhabditis elegans paralogs from all gene families (see Methods). The specific family sequence file is given for internal reference. The number of sequences in each clade and their mean length in codons is given. Key results from codeml analysis are shown for each clade, including the value of the added 11th dN/dS class from model 8 and the delta maximum-likelihood value used for statistical testing. The Bonferoni corrected P-value was computed using a χ-square test with two degrees of freedom. Highly significant evidence of positive selection was found for two clades of srz genes (a more detailed analysis of this family is published elsewhere [6]). Among other families, only one clade of str genes had a marginal significance (set N).
