  • m, length of sequence surveyed (in base pairs); n, number of alleles sampled; S, number of segregating sites; θ and π, Watterson’s (1975) estimator of 4Nμ and the average nucleotide pairwise difference (Nei 1987), respectively. The subscripts t, r, and s mean total sites, replacement sites, and silent sites (synonymous + noncoding sites), respectively.

  • a From Yi and Charlesworth (2000).
