  • Syn, synonymous; nsyn, nonsynonymous; silent, silent in noncoding regions and synonymous in coding regions; S, π, and θ refer to the number of segregating sites, nucleotide diversity (Nei 1987), and the Watterson parameter or expected nucleotide heterozygosity (Watterson 1975), respectively; K is the number of nucleotide substitutions per site, or nucleotide divergence between D. melanogaster and D. simulans, corrected according to Jukes and Cantor (1969).
