Enrichment of heteroplasmic fractions within the dataset. Variants frequency was estimated for eleven ranges of heteroplasmic fractions (HF). The ratio between the mean number of variants for each cluster and the mean number of variants in each sample highlights that homoplasmic variants represent the largest slice with respect to the whole set of alleles in an individual. With respect to the degree of heteroplasmy, there is a substantial preponderance of homoplasmic variants (HF = 1.00), quasi-homoplasmies (0.90-0.99) and low-level heteroplasmies (0.01-0.10).
