In human genetics, a human mitochondrial DNA haplogroup is a haplogroup defined by differences in human mitochondrial DNA. Unlike Y-DNA, which only males can test for, mtDNA testing can be done by both males and females. All mtDNA haplogroups considered native outside of Africa are descendants of either haplogroup M or its sibling haplogroup N. The sequencing of an additional haplogroup P8 mitogenome, together with sequence AY289055 previously thought to belong to haplogroup P6, allowed us to propose a basal haplogroup-P8 motif, as well as the recognition of a subtype P8a, and a TMRCA estimate of this haplogroup. My mitochondrial haplogroup is J1c2f, and I’ll be using this as an example throughout these articles. The clade has played a pivotal role in the early dispersal of anatomically modern humans .
