  • Preferred and unpreferred substitutions are based on Akashi (1995). ymaj/msnon stands for codons that encode a major codon in D. yakuba and a nonmajor codon in the common ancestor of D. melanogaster and D. simulans, and ynon/msmaj represents codons that encode a nonmajor codon in D. yakuba and a major codon in the common ancestor of D. melanogaster and D. simulans.
