From: Fine-scale genetic structure among greater sage-grouse leks in central Nevada
To determine the effect of increased SNP sampling on the precision and information content of population genetic analyses for this system, (a) Procrustes analysis and (b) DAPC were performed for 22 subsets of the total number of SNPs (N = 50, 150, 250, 500, 1 k, 2 k, 3 k, 4 k, 5 k, 6 k, 8 k, 10 k, 12 k, 14 k, 16 k, 18 k, 20 k, 22 k, 24 k, 26 k, 27 k). Ten replicates were analyzed for each subset. Note that approximately 4000 loci are needed to ensure precise estimates of genetic structure (vertical lines depict standard deviations for each parameter estimate).
