Nordic R1a Y-DNA Project

  Nordic R1a Y-DNA Project is a private initiative originating in Norway, which main objective is to use DNA-sequencing of the male Y-cromosome for indicating kinship between members of the haplogroup R1a.

Purpose

The project objectives are:

• To create a base of knowledge on the use of Y-DNA sequencing for detecting relationship between members of the haplogroup R1a, primarily of ethnic nordic origin, secondly of northern european origin
  
• Spread information of its work through various sufficing sources, eg. wikipedia.no and familytreedna.com
  
• Broadcasting knowledge of the haplogroup R1a in general
  
• Recruiting members of the haplogroup R1a for contributing to a R1a database of greater significance
  
• Contributing in the progress of refining subclades of the R1a
  

Status

Background

The inspiration of this project can be attributed to the discussion group (in norwegian) DNA og slektsforskning on DIS-Norges Slektsforum, where a group of its own emanated; The yDNA Haplogroup R1a in Norway.

A process basically based on e-mail exchage carried on consolidating the project, and the project baseline and objectives were drawn out. Furthermore, a list of references to relevant literature and links to relevant resources on the web came to be shared among the initial participants.

What do we know about haplogroup R1a?

R1a (Y-DNA) is one specific sequence of nucleotides in the male Y-cromosome and a Y-cromosome haplogroup identified by the genetic marker M17. R1a rose as a specific mutation in one specific individuals DNA. This individual is considered the origin of all individuals later to carry the R1a, and is decending from haplogroup R1.

R1a is a subclade of Haplogroup R1 (M173).

• Haplogroup R1a (SRY10831.2-)
  • Haplogroup R1a1 (M17)
    • R1a1a M56
    • R1a1b M157
    • R1a1c M64.2, M87 ref
  • Haplogroup R1a*
• Haplogroup R1b (Y-DNA)|Haplogroup R1b]] (M343)

R1a in Norway

I følge Berit Myhre Dupuys et al. artikkel fra 2005 (Ref.2) er haplogruppe R1a en av de tre store yDNA haplogruppene i Norge med 26,3%. De to andre haplogruppene er I med 37,3% og R1b med 31,3%. Haplogruppe R1a er mest vanlig i Midt Norge med 31,5% og minst vanlig på Sørlandet med 13,2%. For størstedelen av landet ligger andelen på over 24%. De seks mest vanlige undergruppene er vist i tabellen nedenfor. For at Dupuys data skal være sammenlignbare med FamilyTreeDNA data, som brukes på denne siden, er følgende justeringer gjort:

Dupuy 389i + 3 = FamilyTreeDNA 389i

Dupuy 389i + 3 + 389ii = FamilyTreeDNA 389ii

De mest vanlige dataene (modal) for R1a i Norge er (Ref. 2):
