Call for Samples

ADMIXTURE's quite sensitive to the variability present in its sample data in order to be more precise about relationships. Representative samples from certain regions would definitely improve the resolution, particularly for smaller components.

Thus I'm asking for 23andme genotype files. Complete anonymity is guaranteed. No health information will be collected from samples, only ancestral info. I will identify each individual only by a tag with country of birth of grandparents and if provided regional origin as well. I do think ADMIXTURE's powerful enough for at least some regional resolution. So if a participant only wants to declare country of birth of his/hers 4 grandparents, that's enough but if you could provide regional origin as well (ie Cornwall, Munster, Bavaria) it would be much more useful.
I'm very interested in samples from Europe, like Ireland (particularly the Western part), UK (all, but more Cornwall, Wales, Scotland Highlands), Finland, Scandinavia (especially Norway), Iceland, Switzerland, Austria (especially Tirol), Slovakia, Carpathians in general (regions of Romania, Poland, etc), Germany, Ukraine, Iberia and France (especially Alps, Massif Central, Pyrenees) with regional identification. Plus people from the Americas with significant known Amerindian ancestry (tribe or regional-tagged please). Also any mountain or island region in the world not represented in my current sample. I know I'm naming several regions with few participants in other projects. So I'm not even mentioning Madagascar, Sami, Indonesia, or Australian samples with known or possible aboriginal origin.
Since I'm anticipating a slow start, I'll probably accept any sample that is tagged with certain regional origin of each grandparent. I'll be making an announcement at 23andme tomorrow (I'm Diogenes412 over there).

So what do I offer? ADMIXTURE analysis in possible Neolithic/Forager element runs I've been publishing. In the future I may be doing more regional and historically more recent stuff as well, if possible.

You can email me at artemisproject.diogenes@gmail.com (or through the blog's email).

    Hopefully it goes without saying that you're welcome to all our data over at Genomes Unzipped. We're currently putting together some data on grandparental origins which we'll also make available soon.

    Do all four grandparents have to be from the same country? I have two from Scotland and two from Holland.

    I'm accepting all regionally identified samples at this time, even if grandparents are from different regions. You can email me the file, if you're comfortable with a regional tag please describe regional origin of grandparents (ie Scottish Lowlands, Highlands or Hebrides).

    Why not make an announcement at the dna-forums too?

    Are you/ will you in the near future accept South Asian samples? I ask this taking this excellent post of yours into consideration - http://dioegenesartemis.blogspot.com/2011/03/third-eurasian-neolithic-revolution.html.

    I'll accept South Asian samples if from the same state/region as for all samples.

    @Diogenes

    Just curious but how come you picked the European countries that you did? I noticed you picked a lot of mountain/highland areas and what you might call the extremes of Europe (or the extreme north and west).

    Would you like the sample of a person whose parents' ancestries both originate from northern Mexico? I only know the name of one of my ancestors' tribes. I must have ancestry from many others, but like many Mexican mestizos, tribal affiliations were lost generations ago.

    If it has substantial Amerindian you may send it regardless of how mixed your ancestry is.
    Please send future such enquiries by email.
