Haplogruppe N (Y-DNA)

In human genetics, Haplogroup N (LLY22G) is a Y-chromosome DNA haplogroup.

This haplogroup appears in Eastern Europe, as well as throughout Russia, northern Scandinavia and Finland.

Haplogroup N is a descendant haplogroup of haplogroup K, and is believed to have first appeared in Siberia thousands of years ago. It was transported across Eurasia by vast movements of Uralic-speaking peoples.

In regards to the geographic origin of Haplogroup N, it is important to note that Y-chromosomes belonging to Haplogroup N as well as undifferentiated or paraphyletic Haplogroup NO* both occur at low frequencies among populations of East Asia, including the Japanese, and that Haplogroup O, which is the "brother" to Haplogroup N in the Y-chromosome phylogenetic tree, is found almost exclusively in East Asia, where it is the modal haplogroup. This may be taken to suggest a prehistoric relationship between the proto-Uralians and most of the ancestors of various peoples who are archaeologically and historically associated with the region of China. However, some commentators have noted that Haplogroup Q, which is the modal haplogroup among Native American populations, as well as Haplogroup R, which is the modal haplogroup among European populations, and even Haplogroup P*, which is ancestral to both Haplogroup Q and Haplogroup R, are found at low to moderate frequency throughout most of East Asia. Thus, the detection of Y-chromosomes that belong to Haplogroup N among populations as geographically and, otherwise, genetically distant as the Finns and the Vietnamese may not necessarily be indicative of a recent common ancestry of the two peoples.

Haplogroup N is the ancestral group for N1, N2, and N3.
