But the spread of R1a-haplogroup amongst Sami in Sweden shows a big span from 10.1% to 36.0%, with an average of 20%, to be compared with Sami in Finland with a span from 9% to 9.9% [6] Because Sami groups in Sweden show differences between haplogroups – such as U5b and V even thought that are mtDNA-groups – in the south of Sweden and in ...
Haplogroup I (M170) is a Y-chromosome DNA haplogroup. It is a subgroup of haplogroup IJ , which itself is a derivative of the haplogroup IJK . Subclades I1 and I2 can be found in most present-day European populations, with peaks in some Northern European and Southeastern European countries.
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.

A Swedish study from 2007 has concluded that the haplogroups U5b1b and V (those which dominate mitochondrial DNA among Sámi from northernmost Sweden, Norway and Finland) likely came to the area very soon after the Ice Age ended. They may have come either from the European continent, or from the Volga-Ural region of Russia, or from both ...
There have been a number of studies about the mitochondrial DNA haplogroups (mtDNA) in Europe. In contrast to Y DNA haplogroups, mtDNA haplogroups did not show as much geographical patterning, but were more evenly ubiquitous. Apart from the outlying Sami, all Europeans are characterized by the predominance of haplogroups H, U and T.
DNA example: strand 1 differs from strand 2 at a single base pair location (a C >> T polymorphism). The following are the technical specifications for known I-M253 haplogroup SNP and STR mutations. Name: M253 [103] Type: SNP Source: M (Peter Underhill of Stanford University) Position: ChrY:13532101..13532101 (+ strand) Position (base pair): 283
(Data from studies conducted before 2004 may be inaccurate or a broad estimate, due to obsolete haplogroup naming systems – e.g. the former Haplogroup 2 included members of the relatively unrelated haplogroups known later as Haplogroup G and macrohaplogroup IJ [which comprises haplogroups I and J].)
Haplogroup C-M217 is the most widespread and frequently occurring branch of the greater (Y-DNA) haplogroup C-M130. Haplogroup C-M217 descendant C-P39 is most commonly found in today's Na-Dene speakers, with the greatest frequency found among the Athabaskans at 42%, and at lesser frequencies in some other Indigenous American groups.
