Strand compositional asymmetry in Copepoda. GC skewness was calculated for 1st plus 2nd (on the left) and 3rd (on the right) codon positions for the 13 protein-coding genes of Copepoda. For each plot, the values for Limulus polyphemus are given. Genes were abbreviated as outlined in the abbreviations section.
