Haplogroup pre-JT
| Haplogroup R2'JT | |
|---|---|
| Possible time of origin | 42,600 to 67,100 YBP |
| Possible place of origin | Probably West Asia |
| Ancestor | R |
| Descendants | R2, JT |
| Defining mutations | 4216 |
Haplogroup pre-JT is a human mitochondrial DNA haplogroup (mtDNA). It is also called R2'JT.
Origin
[edit]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]
Distribution
[edit]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]
Subclades
[edit]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.
