The unique properties of mitochondrial DNA (mtDNA) have made it a useful tool for forensic ... Disease-causing mtDNA mutations differ between mitochondrial lineages, or haplogroups, highlighting the ...

We also carried out mitochondrial DNA haplogroup analysis (for details, see the Supplementary Appendix, available with the full text of this letter at NEJM.org). Of the 2856 subjects, 6 had ...

Lupita Nyongo carries DNA from the oldest maternal haplogroup called Mitochondrial Eve. Lupita Nyongo carries DNA from the oldest maternal haplogroup called Mitochondrial Eve, something we’ve ...

The researchers focused on the disparate geographic distributions of two rare mitochondrial DNA haplogroups — which are characterized by a distinctive DNA sequence derived from a common maternal ...

Mitochondrial DNA mutates at a fairly regular rate over time, and this creates populations who share a common ancestor but have diverged into what are called "haplogroups," or people with a common ...

Haplogroup A2 was the most common, followed by B2 and D1, a trend similar to that reported in the Central Mesoamerican group. Based on the mitochondrial DNA sequence data, the six individuals were ...
