This project is a meeting place for users who share the N1a Mitochondrial DNA haplogroup, which means they are related along their maternal lines. Users in this group may want to share their family trees with each other to find overlaps and merge duplicate profiles in order to join or expand the World Family Tree and discover new relatives.
N1a originated in the Near East 12,000 to 32,000 years ago. Specifically, the Arabian Peninsula is postulated as the geographic origin of N1a. This supposition is based on the relatively high frequency and genetic diversity of N1a in modern populations of the peninsula.Exact origins and migration patterns of this haplogroup are still subject of some debate.
Seven of 42 skeletons from Linear Pottery Culture (Linearbandkeramik) sites were found to be members of the N1a haplogroup (see Neolithic European). N1a was also identified in skeletal remains within a 6200-year-old megalithic long mound near Prissé-la-Charrière, France. A 2500-year-old fossil of a Scytho-Siberian in the Altai Republic, easternmost representative of the Scythians, was found to be a member of N1a1.A study of a 10th and 11th century Hungarians found that N1a1a1 was present in high-status individuals but absent from commoners. One of thirteen skeletons analyzed from a medieval cemetery dated 1250-1450 AD in Denmark was found to be a member of subclade N1a1a.
N1a is a rare haplogroup that currently appears in only 0.2% of European populations. Pockets of higher frequencies exist such as in Croatia where 0.7% of mainland Croatians, 9.24% of the population on the island of Cres, and 1.9% of the population on the island of Brač are members of N1a. In the Volga-Ural region of Russia, N1a is most prominent in the Komi-Permyaks (9.5%) followed by the Bashkirs (3.6%), Chuvash (1.8%), and Tatars (0.4%). In another study of Volga Tatars, haplogroup N1a was found in 1.6% (2/126) of a sample of Mishar Tatars from Buinsk in western Tatarstan (1/126 N1a1a1a1, 1/126 N1a3a3), but it was not observed in a sample of 71 Kazan Tatars from Aznakayevo in eastern Tatarstan, yielding an overall figure of 1.0% N1a (2/197) among Volga Tatars. Russia as a whole has a frequency of 0.7%.
A study of 542 individuals in Portugal found an N1a frequency of 0.37%. Only 0.11% of individuals analyzed in Scotland were members of the haplogroup.
