The numbers of nonancestral mutations, nr, segregating at frequency r in samples of five D. simulans sequences are shown for unpreferred (unpref) and preferred (pref) silent changes, and replacement (rep) mutations. Data were pooled across eight genes: Adh, Adhr, boss, Mlcl, Rh3, per, Pgi, and Zw. See Akashi (1997a) for GenBank accession numbers or references for these data.
