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


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

JT was extremely common among the ancient Etruscans.[2] The haplogroup has also been found among Iberomaurusian specimens dating from the Epipaleolithic at the Taforalt prehistoric site.[3]




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.
