Differential usage of amino acids in the zoarcid species. 4,155 homologue sequence pairs were used for the analyses. All codons with A/T in the third position are labelled with ‘>’; A: The panel displays codons with higher usage frequencies in the Antarctic species; B: Complementary plot for higher usage frequencies in the temperate species.
