  • a Data for total sites are from Kindahl (1994).

  • Data for synonymous sites are from superoxide dismutase (Hudson etal. 1994); transformer (Walthour and Schaeffer 1994); Mlc1 (Leicht etal. 1995); Gld(Hamblinand Aquadro 1997); larval cuticle protein Ψ (Pritchard and Schaeffer 1997); Acp26Aa and Acp26Ab (Aguade etal. 1992); triose phosphate isomerase (Hasson et al. 1998); and rosy, esterase 6, ornithine dehydrogenase, larval serum protein 1-γ (all unpublished data from V. L. Bauer and C. F. Aquadro).

  • b Data for both total and synonymous sites are from this study and Schaeffer and Miller (1992a).
