Haplogroup L2 is a human mitochondrial DNA (mtDNA) haplogroup with a widespread modern distribution, particularly in Subequatorial Africa. Its L2a subclade is a somewhat frequent and widely distributed mtDNA cluster on the continent, as well as among those in the Americas.

2015年7月27日 · Mitochondrial DNA (mtDNA) haplogroup L2 originated in Western Africa but is nowadays spread across the entire continent. L2 movements were previously postulated to be related to the Bantu...

This is where your direct maternal haplogroup is most commonly found today based on self-reported information from hundreds of thousands of mtDNA testers and participants in academic studies. This page shows the general regions where people with the same mtDNA as …

Haplogroup L2a is the most common and widely distributed sub-Saharan African haplogroup and is also frequent in the Americas (∼19%). The wide distribution of L2a in Africa makes identifying geographical origins of lineages difficult.

The main puzzle is the almost ubiquitous haplogroup L2a, which we suggest may have become prevalent somewhere in north Central Africa, spreading both east and west along the Sahel belt ∼20,000 years ago at the peak of the LGM (or somewhat earlier).

The very central African populations, mostly Pygmy groups, present low proportions of L2 lineages in its pool. This pattern is caused mainly by sub-haplogroup L2a, the most frequent lineage in L2, while L2b, L2c and L2d attain highest proportions in the west coast between Senegal and Mauritania. Figure 5.

2008年4月9日 · To elucidate the origin of African-specific mtDNA lineages, revealed previously in Slavonic populations (at frequency of about 0.4%), we completely sequenced eight African genomes belonging to...

2015年4月2日 · L2 is an mtDNA Haplogroup. This phylogenetic tree of haplogroup L2 subclades is based on the paper by Mannis van Oven and Manfred Kayser Updated comprehensive phylogenetic tree of global human mitochondrial DNA variation [PMID 18853457] and subsequent published research.
