Distributions of minor allele frequencies for successful Douglas-fir SNPs. Open bars represent successful SNPs, whereas solid bars represent successful SNPs that were in Hardy-Weinberg Equilibrium (HWE; P ≥ 0.01). Successful SNPs were SNPs that were polymorphic and had SNP call rates > 60%. Minor allele frequencies are averaged across two populations of unrelated trees (C1 = 112 trees and C2 = 283 trees)
