Cornwall, Kent, and Orkney

I just finished extracting the regional samples (Kent, Cornwall, and Orkney) from the 1000 Genomes GBR sample, and I made a quick experiment to put them in context of other West European populations (Irish, German, Dutch, French, and Scandinavian).
I will probably try to integrate some of these to the new version of Dodecad, and try some other things, so perhaps v2 may not be the next stage of the Project. Hopefully the extra wait will be worth it.

UPDATE:

Here is also a supervised ADMIXTURE analysis with the standard K=10 components. Please note that as this is not done with the same SNPs as the standard K=10 results, they are not comparable directly to other K=10 results of the Project.

    My maternal grandfather was born and raised in the Orkney Islands, and I'm curious if this would be detected?

  2. I'd love to know where DOD098 (Father) and DOD099 (Mother) are, as my father typically is near the Scandinavians and mother centered on the Irish.

    Is it possible to post coordinates, or send them to me - thanks!

  3. What a great job you do here! Congratulations!
    I just got to your site and couldn't find any tutorial. What should I do? Send you the raw data from 23andMe? Is that it?
    Thanks,

    Mario

  5. It is strange that the Orkney samples are so distant from the Scandinavian ones considering that the Orkney Islands were settled by the Vikings.

  6. @AverageJoe,

    The Orkneys are a mix of Celtic and Viking and more importantly have a small but significant Native American contribution - as many Orkyneyar worked for the Hudson Bay Company in Northern Canada, and brought their Cree/Ojibwa wives back home with them.

  7. Conroy, like the rest of British and Irish people, Orcadians (=people of Orkney) don't have any Mongoloid component according to the genetic analyses. So your Cree/Ojibwa admixture theory is scientifically unsupported.

  8. onur - your are incorrect (again). I am reporting a fact, not a theory.

    No, you are theorizing. Your theory is this: the part of Orcadians who worked for the Hudson Bay Company, married Native American women and then turned back to the homeland was so large to have a discernable effect on the Orcadian genetics. But your theory is refuted by genetics. BTW, adding the word "again" to your sentence does not mean anything, as you haven't proven me wrong so far.

  10. Conroy, like the rest of British and Irish people, Orcadians (=people of Orkney) don't have any Mongoloid component according to the genetic analyses.

    BTW, for those who don't know, I consider components or sum of components that are roughly 0.5% or below as practically non-existent (they are very probably just noise; even if they aren't noise, they are very close to absolute zero). The sum of the Mongoloid components of the overwhelming majority of Europeans (including Orcadians, general British and Irish) are in practically non-existent levels instead of absolute zero, and for practicality I consider them as lacking the Mongoloid components. According to Dienekes' most recent analysis, the sum of the Mongoloid components of the HGDP Orcadians is just 0.3%, and this is equal to the sum of the Mongoloid components of the HGDP French, Dodecad Sicilians and Spanish and just 0.1% more than that of the Dodecad British.

  11. Hello,
    I am confused! Please excuse my ignorance but I have only just stumbled into GED match and also only had my AncestryDNA done a couple of months ago. My Ancestry results are:

    Scandinavian- 24%
    GB - 23%
    Western European - 23&
    Irish - 20%
    Iberian Peninsula - 7%
    Italy/Greece - 2%
    Middle East - 1%

    Here is my Dodecad result:
    # Population Percent
    1 West_European 51.86
    2 Mediterranean 25.58
    3 East_European 11.16
    4 West_Asian 7.51
    5 Southwest_Asian 2.1
    6 South_Asian 0.92
    7 Northeast_Asian 0.51
    8 Northwest_African 0.32
    9 Neo_African 0.04

    AncestryDNA do not explain your ancient DNA - only a short history lesson on the areas they have predicted for your DNA ethnicity. Gedmatch (where I did the Dodecad test - with my Ancestry DNA raw data) is way over my head- but I am trying to make sense of it. It seems to sway heavily to my European percentages, however in the breakdown it states that I have majority of up to 96% CEU which I believe is Scandinavian/Baltic. Is this ancient DNA? how far back is this test? is it over 1 thousand years? ..as AncestryDNA is supposed to go over 500-1000 years. If anyone can help me I would appreciate it
    Thanks, Kerry
