In human mitochondrial genetics, haplogroup JT is a mitochondrial DNA (mtDNA) haplogroup.

Origin

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 at the Taforalt prehistoric site.^[3]
