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 ancient Etruscans.[2] The haplogroup has also been found among Iberomaurusian specimens.[3]
Subclades
Tree
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.
