In human mitochondrial genetics, Haplogroup L0 is a human mitochondrial DNA haplogroup.


L0 is one of two branches from the of the most recent common ancestor, MRCA, for the shared human maternal lineage. This ancestor is estimated to have lived in Southern Africa or East Africa approximately 150,000 to 170,000 years ago. Haplogroup L0 consists of five main branches (L0a, L0b, L0d, L0f, L0k). Four of them were originally classified into haplogroup L1 as L1a, L1d, L1f, and L1k.


It is found most commonly in the Sub-Saharan Africa. It reaches its highest frequency in the Khoisan people at 73%. Some of the higher frequencies are: Namibiamarker (!Xun) 79%, Southafrica (Khwe/!Xun) 83% and Botswanamarker (!Kung) 100%.

Haplogroup L0a is most prevalent in South-East African populations (25% in Mozambiquemarker).Among Guineansmarker, it has a frequency between 1% and 5%, with the Balanta group showing increased frequency of about 11%. Haplogroup L0a has a Paleolithic time depth of about 33,000 years and likely reached Guinea between 10,000 and 4,000 years ago. It also is often seen in the Mbuti and Biaka-pygmies.

Haplogroup L0b Ethiopia.

Haplogroup L0f is present in relatively small frequencies in Tanzania, East Africa.

Haplogroups L0d and L0k are the most ancient ones and are typical for Khoisans in South Africa.



This phylogenetic tree of haplogroup L0 subclades is based on the paper by Mannis van Oven and Manfred Kayser Updated comprehensive phylogenetic tree of global human mitochondrial DNA variation and subsequent published research.
