Nucleotide diversity and divergence in the lbe gene region of D. melanogaster.

Note. — Calculations based on 70 D. melanogaster lines from three populations: Barcelona, El Rio (California) and Venezuela, plus three lines from Zimbabwe and one lbe sequence from GenBank (accession number NT_033777.2). N, number of sites (indels excluded); S, polymorphic sites (number of singletons in parentheses); π, average number of nucleotide differences per site among all pairs of sequences [104, p. 256]; θ, average number of segregating nucleotide sites among all sequences, based on the expected distribution of neutral variants in a panmictic population at equilibrium [105]; Kmel-sim, Kmel-sec, and Kmel-yak refer to nucleotide differences between D. melanogaster and D. simulans, D. sechellia or D. yakuba, respectively; Syn, synonymous sites; Nsyn, nonsynonymous sites; Ncod, noncoding (intronic and flanking regions); Silent, silent sites (synonymous and noncoding sites).
