N Y-DNA Haplogroup Project- Background



To view the latest cladogram results it can be found here

Haplogroup N is defined by a SNP-mutation from G to A called M231 at the Y-chromosome that appeared in a man that was the common ancestor of all haplogroup N people of today. This founding father may have lived as long as 20 000 to 30 000 years ago. This common father may have lived in todays Sout-East-Asia. The Y-DNA haplogroup N has a wide distrubution primarly in northern-eurasia often associatied (but not necessarly) with current and earlier Uralic speakers in Europe. All Y-chromosome haplogroup N holders from all the world, predicted or SNP tested welcome.

The first myth about haplogroup N I want to burst right away, most of it in Europe did not come in recorded history from the Huns and the Mongols. I quote Rootsi at University of Tartu, Estonia who is leading the research on hg N. The age of hg N3 in the Finnic-Ugric speaking population in eastern Europe suggest a much earlier arrival from the east. "From the archaeological point of view, hg N3 is spread in Europe i the area of comb-ceramic culture. It is not, however, obvious that the spread of the two can be temoporily connected, because STR diversity-based calculations of the time depth of hg N3 among the Finnick-speaking European population suggests expansion time before-around the end of pleistoscene - that is long before the rise of the comb-ceramic cuture in the 4th millennium BC" Source: Rootsi 2004

Y-chromosomal DNA is passed from father to son only and follow a stright direct paternal line. This means that the Y-DNA you have carry only apply for 1 of your 512 forefathers in your 10th generation back, this fraction will be even smaller as you go further back. The remaining 511 forefathers could probably belong to other haplogroups and/or having their own haplotypes, however depending on what population you belong to it should be possible to infer ruffly what haplogroups your total numbers of forefathers carried. If most of your geneology are from Britain haplogroup N would only count for a extremly small fraction of your ancestors. If your a Finn haplogroup N would count for over half of your male forefathers, eventually depending on what population you belong to, your total haplogroup frequency would look similar to the weighted average of the populations your ancestor belonged too.

What haplogroup or subclade of the haplogroup you belong to can be determined in two different ways 1) by Y-SNP and 2) by prediction using Y-STR markers. Using Y-SNP categorize your haplogroup with certainty and using Y-STR categorize your haplogroup reasonably accurate with statistics because Y-STR haplotypes correlate with Y-SNP in most cases. FTDNA uses by default prediction but do offer deep subclade and LLY22G/M231 backbone SNP test. The Y-SNP mutate rarely on the same spot. We are talking mostly about thousands of years. The Y-STR on the other hand mutate more rapidly and have more markers and are more useful to determine closer relationship within the last thousand years. Optimal combination are using both Y-SNP and Y-STR test because it is then possible to exclude similarity by state in the Y-STR, for example two persons with N1c1 and N1c1a with identical Y-STR haplotype is much more distant related then what the identical haplotype suggest.

Haplogroup N subclades are currently defined with these main overhad SNP. These are included in FTDNA's current N subclade test:

N* (M231)
N1 (LLY22g)
N1a (M128)
N1b (P43)
N1b1 (P63)
N1c (M46/Tat,P105)
N1c1 (M178, P298)
N1c1a (P21)
N1c1b (P67)
N1c1c (P119)

Do you need to do a subclade test? Not neccessarly. If someone with a identical or almost identical Y-STR haplotype already have tested you can instead rely on FTDNA's prediction with high confidence. To investigate this logon to your FTDNA account and click "Y-DNA" and submeny "Haplotree". Then at the upper right click "Matches". If you have any "Exact matches" within f.ex "N1c1" or any other configuration other than N or N1 you likely do not need to do a subclade test.
