Plots of the variants called in the DNA samples. (A) Total number of variants found in the samples. (B) False discovery rate - the number of variants that were not in the genomic DNA. (C) The number of variants that match with the genomic DNA. (D) Heterogeneity to homogeneity ratio of the variants found. X-axis abbreviations: gDNA = genomic DNA, WGAgDNA = Whole genome amplification done on gDNA, WGA 50 cell whole genome amplification done on 50 cells, NF = not fixed, F = fixed.
