Haplogroup pre-JT is a human mitochondrial DNA haplogroup (mtDNA). It is also called R2'JT.
Haplogroup pre-JT is a descendant of the haplogroup R. It is characterised by the mutation T4216C. The pre-JT clade has two direct descendant lineages, haplogroup JT and haplogroup R2.[ citation needed ]
According to YFull MTree, haplogroup R2'JT has allegedly been sequenced in at least three individuals, among whom one came from ancient Egypt [1] and one from modern Denmark. [2] However, Ian Logan mutationally interpreted the Denmark sample as being a member of T1a. [3]
One carrier of haplogroup R2'JT was found in an in-depth study of "108 Scandinavian Neolithic individuals". [4]
Its major subclade is Haplogroup JT, which further divides into Haplogroup J and Haplogroup T. Its other subclade is Haplogroup R2, which has such branches as R2a, R2b, and R2c.

Haplogroup J is a human mitochondrial DNA (mtDNA) haplogroup. The clade derives from the haplogroup JT, which also gave rise to haplogroup T. Within the field of medical genetics, certain polymorphisms specific to haplogroup J have been associated with Leber's hereditary optic neuropathy.
Haplogroup HV is a human mitochondrial DNA (mtDNA) haplogroup.
Haplogroup U is a human mitochondrial DNA haplogroup (mtDNA). The clade arose from haplogroup R, likely during the early Upper Paleolithic. Its various subclades are found widely distributed across Northern and Eastern Europe, Central, Western and South Asia, as well as North Africa, the Horn of Africa, and the Canary Islands.
In human mitochondrial genetics, Haplogroup C is a human mitochondrial DNA (mtDNA) haplogroup.
Haplogroup L2 is a human mitochondrial DNA (mtDNA) haplogroup with a widespread modern distribution, particularly in Subequatorial Africa. Its L2a subclade is a somewhat frequent and widely distributed mtDNA cluster on the continent, as well as among those in the Americas.
In human mitochondrial genetics, Haplogroup Z is a human mitochondrial DNA (mtDNA) haplogroup.
Haplogroup I is a human mitochondrial DNA (mtDNA) haplogroup. It is believed to have originated about 21,000 years ago, during the Last Glacial Maximum (LGM) period in West Asia. The haplogroup is unusual in that it is now widely distributed geographically, but is common in only a few small areas of East Africa, West Asia and Europe. It is especially common among the El Molo and Rendille peoples of Kenya, various regions of Iran, the Lemko people of Slovakia, Poland and Ukraine, the island of Krk in Croatia, the department of Finistère in France and some parts of Scotland and Ireland.
In human genetics, a human mitochondrial DNA haplogroup is a haplogroup defined by differences in human mitochondrial DNA. Haplogroups are used to represent the major branch points on the mitochondrial phylogenetic tree. Understanding the evolutionary path of the female lineage has helped population geneticists trace the matrilineal inheritance of modern humans back to human origins in Africa and the subsequent spread around the globe.
Haplogroup JT is a human mitochondrial DNA (mtDNA) haplogroup.
In human mitochondrial genetics, haplogroup E is a human mitochondrial DNA (mtDNA) haplogroup typical for the Malay Archipelago. It is a subgroup of haplogroup M9.
Haplogroup L0 is a human mitochondrial DNA (mtDNA) haplogroup.
In human mitochondrial genetics, haplogroup Q is a human mitochondrial DNA (mtDNA) haplogroup typical for Oceania. It is a subgroup of haplogroup M29'Q.
In human mitochondrial genetics, Haplogroup G is a human mitochondrial DNA (mtDNA) haplogroup.
In human mitochondrial genetics, the Haplogroup CZ is a human mitochondrial DNA (mtDNA) haplogroup.
Haplogroup L4 is a human mitochondrial DNA (mtDNA) haplogroup. It is a somewhat uncommon maternal clade primarily found in East Africa.
Haplogroup L5 is a human mitochondrial DNA (mtDNA) clade. It was previously known as L1e.
In human mitochondrial genetics, Haplogroup L6 is a human mitochondrial DNA (mtDNA) haplogroup. It is a small African haplogroup.
Haplogroup H is a human mitochondrial DNA (mtDNA) haplogroup. The clade is believed to have originated in Southwest Asia, near present day Syria, around 20,000 to 25,000 years ago. Mitochondrial haplogroup H is today predominantly found in Europe, and is believed to have evolved before the Last Glacial Maximum (LGM). It first expanded in the northern Near East and Southern Caucasus, and later migrations from Iberia suggest that the clade reached Europe before the Last Glacial Maximum. The haplogroup has also spread to parts of Africa, Siberia and Inner Asia. Today, around 40% of all maternal lineages in Europe belong to haplogroup H.
In human mitochondrial genetics, Haplogroup K1a1b1a is a human mitochondrial DNA (mtDNA) haplogroup.
Haplogroup O mtDNA is a haplogroup derived from haplogroup N and found in Oceania. Specifically, it is found among Aboriginal Australians. Its defining mutations are G6755A, C9140T, and G16213A.
