Example of SNP loci failed to pass QC: a) call rate < 95%; b) cluster separation < 0.40; and SNP loci met QC requirements: c) cluster separation = 0.41 and d) call rate 100%, cluster separation = 1.00. Figure S2. Box-plot showing estimated variation of theta in two sets of SNPs with cluster separation score < 0.4 and > 0.4 for (a) array and (b) pool construction replicates (both tests, Mann–Whitney U test, P < 0.0001). Horizontal line, grey square, whiskers, open circles, and stars indicate median, 25th and 75th quartiles, non-outlier range, outliers and extreme outliers, respectively. Figure S3. A significant negative correlation between (a) array-(Pearson’s r = − 0.346, P < 0.0001) and (b) pool-construction (Pearson’s r = − 0.246, P < 0.0001) variation and cluster separation scores. Figure S4. Proportion of loci remained in each allele frequency class after application of (a) uniform and (b) spherical filter.
