Figure 2From: Distinctive mitochondrial genome of Calanoid copepod Calanus sinicus with multiple large non-coding regions and reshuffled gene order: Useful molecular markers for phylogenetic and population studiesStrand 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.Back to article page
