Comparison of genotype call accuracy related to input DNA copy number. Three genomic DNA samples carrying different genotypes with varied input amount were genotyped on SNP rs513349. The scatter plots of different DNA copy number ends in each reaction chambers are shown, (a) 0.9 copies; (b) 4.5 copies; (c) 9 copies; (d) 45 copies; (e) 90 copies.
