Haplogroup L0 (mtDNA)
The geographic origins of populations can be identified by their maternally inherited mitochondrial DNA (mtDNA) haplogroups
Haplogroup L0a is most prevalent in South-East African populations (25% in Mozambique).[6] Among Guineans, 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. L0a is found at a frequency of almost 25% in Hadramawt (Yemen)
