Haplogroup JT is a human mitochondrial DNA (mtDNA) haplogroup.

Haplogroup JT
Possible time of origin50,300 YBP
Possible place of originSouthwest Asia
DescendantsJ, T
Defining mutations11251, 15452A, 16126[1]


Haplogroup JT is descended from the macro-haplogroup R. It is the ancestral clade to the mitochondrial haplogroups J and T.

JT (predominantly J) was found among the ancient Etruscans.[2] The haplogroup has also been found among Iberomaurusian specimens dating from the Epipaleolithic at the Taforalt prehistoric site.[3] One ancient individual carried a haplotype, which correlates with either the JT clade or the haplogroup H subclade H14b1 (1/9; 11%).[4]




This phylogenetic tree of haplogroup JT subclades is based on the paper by Mannis van Oven and Manfred Kayser Updated comprehensive phylogenetic tree of global human mitochondrial DNA variation[1] and subsequent published research.
