From: Ratio of mitochondrial to nuclear DNA affects contamination estimates in ancient DNA analysis
Variation in the mt/nc ratios between skeletal elements. (A) Box plots of the mitochondrial to nuclear DNA ratio (log-transformed) of human DNA in petrous bones (P), teeth (T), other bones (B) and controls. Panel (B) shows density plots of the same data across elements. Orange lines indicate the suggested threshold of the mitochondrial to nuclear ratio of 200 (loge(200) = 5.3).
