Fig. (2) Screen captures from GeneMapper software v3.5 of three samples belonging to three different European mtDNA haplogroups. A) Single Base Extension (SBE) assay for a sample with the haplogroup H. B) SBE assay for a sample with the haplogroup J. C) SBE assay for a sample with the haplogroup T. The first peak on the left corresponds to the size standard of 25 bp. Y axe corresponds to the signal intensity (in Relative Fluorescence Units or rfus) and X axe corresponds to the size (pb).
