Haplogroup pre-JT is a human mitochondrial DNA haplogroup (mtDNA). It is also called R2'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 |
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]
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.
