  • a Values of π and θ were multiplied by 103; values in parentheses are for synonymous and noncoding sites only.

  • b Values in parentheses were determined using the D. yakuba sequence as an outgroup.

  • c janA, janB, and ocn only.

  • π, average number of pairwise differences (Tajima 1983); θ, estimator of 4Nμ (Watterson 1975); hdiv, haplotype diversity (Nei 1987); sub(i, j), the most extreme subset of the sample, where i and j are the number of alleles and number of segregating sites in the subsample, respectively (Hudson et al. 1994). Significance levels were determined by 10,000 random coalescent simulations conditioned on the observed number of alleles and segregating sites and assuming no recombination. janB includes the region labeled “intergenic” in Figure 2. *P < 0.05; **P < 0.01.
