Fig. 1 The x-axis shows the mean peak height (in rfu) for each heterozygote genotype. The y-axis shows the ratio between the smaller and the larger peak height, respectively. The red horizontal line at the 0.6 ratio marks the limit below which the alleles are considered unbalanced. (For interpretation of the references to color in this figure legend, the reader is referred to the web version of this article.)

Fig. 2 Allele and locus dropout heat map using a limit of detection threshold (LDT) set at 50rfu. The x-axis shows the samples names of the experiments. The names are a coded description of the experiment, where the coding is n∙VPCR∙VDNA, and indicates respectively the number of cycles (n), the volume in μl of the solution in which the PCR reaction was made (VPCR), and the volume in μl of the DNA solution used in the experiment (VDNA). On the y-axis the 16 Markers of the Identifiler kit are reported.
