Haplogroup J (mtDNA)
Haplogroup J is a human mitochondrial DNA (mtDNA) haplogroup. The clade derives from the haplogroup JT, which also gave rise to haplogroup T. In his book ''The Seven Daughters of Eve'', Bryan Sykes named the originator of this mtDNA haplogroup ''Jasmine''. Within the field of medical genetics, certain polymorphisms specific to haplogroup J have been associated with Leber's hereditary optic neuropathy. as well as Sudanese Copts (10.3% J1a; 10.3% J2), Sudanese Fulani (10.7% J1b), Meseria (6.7% J1b), Arakien (5.9% J1b), Egyptians (5.9%), Mozabite Berbers (3.53%), Sudanese Hausa (2.9% J1b), Zenata Berbers (2.74%), Beja (2.1% J1b), and Reguibate Sahrawi (0.93%). Within Europe, >2% frequency distribution of mtDNA J is as follows: *J* = Ireland — 12%, England-Wales — 11%, Scotland — 9%, Orkney — 8%, Germany — 7%, Russia (European) — 7%, Iceland — 7%, Austria-Switzerland — 5%, Finland-Estonia — 5%, Spain-Portugal — 4%, France-Italy — 3% *J1a = Austria-S ...
