Fig. 1 On the left, STR locus of skin–blood mixtures in which both donors are heterozygote. Peaks are balanced and 1:1, 1:10, 1:20 ratios are in accordance with the expectation. [Blood (28, 31); Skin (30, 33.2)]. (For interpretation of the references to color in this figure legend, the reader is referred to the web version of this article.) On the right mtDNA variants in blood–skin and saliva–skin samples. mtDNA ratios are different from expected results. Where the STR profile appears as a 1:1 ratio, skin mtDNA amount is about three times higher than the expected, and this condition is maintained in each dilution (for more detailed information look at peaks height display under each SNP). The only exception is saliva–skin 1:1, where SNP peaks height is more or less balanced between two donors (orange circle).
