S, number of segregating sites; η, total number of mutations; π, nucleotide diversity; πS, silent nucleotide diversity; both noncoding positions and synonymous sites in the coding region were used to estimate πS (Nei and Gojobori 1986; Nei 1987); NS, not significant.

  • a Average nucleotide divergence between D. simulans and D. melanogaster corrected by the Jukes and Cantor (1969) method.

  • b Average silent nucleotide divergence between D. simulans and D. melanogaster corrected by the Jukes and Cantor (1969) method.
