In human mitochondrial genetics, Haplogroup L6 is a human mitochondrial DNA (mtDNA) haplogroup. It is a small African haplogroup.[3]

Distribution

Projected spatial frequency distribution for haplogroup L6.
Schematic tree of mtDNA haplogroup L6 (and L4). Ages (in ka) indicated are maximum likelihood estimates obtained for the whole-mtDNA genome.

This haplogroup has been found most often in Yemen and Ethiopia.[4]
