Five copepods, the PCGs of which have been entirely determined, were selected for interspecific analysis. For the PCGs, divergence of amino acid was compared for the interspecific analyses, and the nucleotide divergence was outlined for the intraspecific comparisons. Ratios of non-synonymous to synonymous substitutions for the 13 PCGs were compared. Genes were labelled as outlined in the abbreviations section. DB and ωB: p-distance and dN/dS among five copepods; DW and ωW: p-distance and dN/dS within C. sinicus.

1 missing data due to the incomplete dataset;

2 unfeasible parameter for the corresponding genes.
