Summary of locus characteristics for <i>D. tenebrosus</i> by region (British Columbia, 12 populations pooled), North Cascades and South Cascades.

n = sample size of individuals, A = number of alleles, He = expected heterozygosity, Ho = observed heterozygosity, Null = estimated null allele frequency (Oosterhout method), and the number of private alleles per locus and their frequency range for each region. Results of Hardy-Weinberg (HW) equilibrium tests are presented for British Columbia as the number of populations with significant deviation from HW expectations (P<0.05 after Bonferroni correction). Within the North Cascades and the South Cascades, P-values of HW tests are presented for each locus. * = significant deviation from HW equilibrium after Bonferroni correction. † = evidence for null alleles at this locus. See Table S1 for population-level locus characteristics in British Columbia.
