Haplogroup A2 is the most common haplogroup among the Inuit, Na-Dene, and many Amerind ethnic groups of North and Central America. Lineages belonging to haplogroup A2 also comprise the majority of the mtDNA pool of the Inuit and their neighbors, the Chukchis, in northeasternmost Siberia. [5] [6] [7]
[12] [84] This suggests that 95% of Indigenous American mtDNA is descended from a minimal genetic founding female population, comprising sub-haplogroups A2, B2, C1b, C1c, C1d, and D1. [85] The remaining 5% is composed of the X2a, D2a, C4c, and D4h3a sub-haplogroups. [84] [85] X is one of the five mtDNA haplogroups found in Indigenous Americans.
Haplogroup A2 is the main Native American haplogroup in Cuba (21.9% of the total sample), accounting for 67% of the Native American mtDNA gene pool. Regarding Y-chromosome haplogroups (male lineages), 78.8% of the sequences found in Cubans are of West Eurasian origin, 19.7% of African origin and 1.5% of East Asian origin.
This is a purported list of ancient humans remains, including mummies, that may have been DNA tested. Provided as evidence of the testing are links to the mitochondrial DNA sequences, and/or to the human haplogroups to which each case has been assigned.
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.
