Haplogroup L2 (mtDNA)

Haplogroup L2 (mtDNA)

In human genetics, Haplogroup L2 is a human mitochondrial DNA (mtDNA) haplogroup.

Haplogroup L2 is native to sub-Saharan Africa, where it is present in approximately one third of all people. It is believed to have arisen between 87,000 to 107,000 years ago. [Tishkoff et al., Whole-mtDNA Genome Sequence Analysis of Ancient African Lineages, Mol. Biol. Evol, 24(3):757-68. 2007]

ubdivisions

L2 has four main subgroups: L2a, L2b, L2c, and L2d.

Haplogroup L2a

The most common L2 subgroup, L2a, is also the most common haplogroup among African Americans.
