  • Odds ratios refer to the Akashi test on the genomes of each species calculated for: all, overall transcripts; domains, transcript segments covering protein domain regions; nondomains, transcript segments covering nondomain regions; stems, transcript portions containing codons with the third base in a stem region; and loops, transcript portions containing codons with the third base in a loop region. D, codons in protein domain regions; ND, codons in protein nondomain regions; S, codons with the third base in a stem region; L, codons with the third base in a loop region; ns, nonsignificant.
