  • AAx-y, region coding for amino acid residues x through y. Fs, number of synonymous fixed differences between species; Fns, number of nonsynonymous fixed differences between species; Ps, number of synonymous segregating sites; Pns, number of nonsynonymous segregating sites. mel, all D. melanogaster lines; sim, D. simulans; mau, D. mauritiana; sech, D. sechellia. Probability established with a G-test with Williams’ correction for continuity. *0.01 < P < 0.05; **0.001 < P < 0.01; ***P < 0.001.
