Haplogroup L3 is a human mitochondrial DNA (mtDNA) haplogroup. The clade has played a pivotal role in the early dispersal of anatomically modern humans . It is strongly associated with the out-of-Africa migration of modern humans of about 70–50,000 years ago.
An African American man, who was sampled in 2013, carried haplogroup A00, which likely dates back to 338,000 BP, and is a haplogroup shared with the Mbo people. [32] Torres et al. (2012) states: "One African American population, those from South Carolina, cluster with the African populations.
Haplogroup L lineages are found in the African diaspora of the Americas as well as indigenous Americans. Haplogroup L lineages are predominant among African Americans, Afro-Caribbeans and Afro-Latin-Americans. In Brazil, Pena et al. report that 85% of self-identified Afro-Brazilians have Haplogroup L mtDNA sequences. [38]
The characteristic West African haplogroups L1b, L2b,c,d, and L3b,d and West-Central African haplogroups L1c and L3e in particular occur at high frequencies among African Americans. As with the paternal DNA of African Americans, contributions from other parts of the continent to their maternal gene pool are insignificant.
The proportions of various human Y-DNA haplogroups vary significantly from one ethnic or language group to ... South African Whites: Indo-European: 157 0 0 0.6 0.6 9. ...
Haplogroup A is a human Y-chromosome DNA haplogroup, which includes all living human Y chromosomes.Bearers of extant sub-clades of haplogroup A are almost exclusively found in Africa (or among the African diaspora), in contrast with haplogroup BT, bearers of which participated in the Out of Africa migration of early modern humans.
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 .
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.
