Haplogroups are used to represent the major branch points on the mitochondrial phylogenetic tree. Understanding the evolutionary path of the female lineage has helped population geneticists trace the matrilineal inheritance of modern humans back to human origins in Africa and the subsequent spread around the globe. The letter names of the ...
A2 is found in Chukotko–Kamchatka [5] and is also one of five mtDNA haplogroups found in the indigenous peoples of the Americas, the others being B, C, D, and X. [4] Haplogroup A2 is the most common haplogroup among the Inuit, Na-Dene, and many Amerind ethnic groups of North and Central America.
Haplogroup H is a human mitochondrial DNA (mtDNA) haplogroup. The clade is believed to have originated in West Asia , near present day Syria, [ 1 ] around 20,000 to 25,000 years ago. Mitochondrial haplogroup H is today predominantly found in Europe, and is believed to have evolved before the Last Glacial Maximum (LGM).

In human mitochondrial genetics, L is the mitochondrial DNA macro-haplogroup that is at the root of the anatomically modern human (Homo sapiens) mtDNA phylogenetic tree. As such, it represents the most ancestral mitochondrial lineage of all currently living modern humans, also dubbed "Mitochondrial Eve".
A haplotype is a group of alleles in an organism that are inherited together from a single parent, [1] [2] and a haplogroup (haploid from the Greek: ἁπλοῦς, haploûs, "onefold, simple" and English: group) is a group of similar haplotypes that share a common ancestor with a single-nucleotide polymorphism mutation. [3]
Like its sibling macrohaplogroup M, macrohaplogroup N is a descendant of the haplogroup L3. All mtDNA haplogroups found outside of Africa are descendants of either haplogroup N or its sibling haplogroup M. M and N are the signature maternal haplogroups that define the theory of the recent African origin of modern humans and subsequent early ...
Phylogenetic tree of haplogroups I (left) and W (right). Kya in the left scale bar stands for thousand years ago. This phylogenetic tree of haplogroup W subclades is based on the paper by Mannis van Oven and Manfred Kayser Updated comprehensive phylogenetic tree of global human mitochondrial DNA variation [2] and subsequent published research.
