Codon usage of the protein-coding genes in the mitochondrial genomes of <i>Psococerastis albimaculata</i> and <i>Longivalvus hyalospilus</i>.

a<p>A+T-rich codons are those encoding amino acids Asn, Ile, Lys, Met, Phe, and Tyr.</p>b<p>G+C-rich codons are those encoding amino acids Ala, Arg, Gly, and Pro.</p>c<p>Codon ratio is G+C-rich codons/A+T-rich codons.
