Table 2. Diversity and expansion metrics for the reduced control region dataset (634 bp control region) for inferred lineages (Central, East, Midwest, and Southwest) and the total dataset (Total). We report the same metrics as the total dataset: number of individuals (n), number of haplotypes (h), haplotype diversity (hD), nucleotide diversity (π), average pair-wise nucleotide differences (k), Fu’s Fs (Fs), and Tajima’s D (D). Both Fu’s Fs and Tajima’s D were negative, with only Fs being significant (bold).
