North German and scandinavian can be blended. Iberian Italian and Greek can be blended or divided. It might be more important to look for a North South or East West split rather then particular populations.
    I wouldn't say I know my full ethnic background, but I know I'm around 1/3 Irish, mostly English and then possibly South West European or maybe even Norwegian going further back (judging by where matches are and what estimates have told me).

    Lana, with my "little model" (Swedish_BAC, Swedish_Mega,etc) you "are" nearly indistinguishable from two England_Saxons:

    England_Saxon3,82.2,0.0,17.8,0.0,0.0
    lana6765,81.4,0,18.6,0,0

    In my opinion, a very simple model with a few ancient reference high-covered samples, chosen as orthogonal as possible, is the only reliable way to explore your ancestry with G25.

    But doesn’t that kind of mean G25 can’t really tell me anything though?

    I mean I know I’m mostly English and Irish, but if it can’t confirm or refute Southern European or smaller amounts of other ethnicities, then why use it?

    I guess if I remove Russia things get less Irish. But then I still don't get English.

    And if I only include the places I know I have ancestry from, or think I might, things get even more Irish than ever, with very little English at all!

    Without French:
    Target: lana6765

    72.0 Irish
    27.0 French_Pas-de-Calais
    1.0 French_Seine-Maritime

    Also, isn't this sort of confirmation bias?
    That happens to my results when I remove Norwegian.

    It can confirm, just use only English, Irish and Spanish average samples. Also you weird score is on Unscaled, do not pay attention to it

    Because it allows you to interact with Ancient samples, and learn more about all this DNA stuff by having tools where you can manipulate it and work with it.
    Frankly, IMO if you just want to know what you are take the more reliable of the commercial tests. If you're looking for something exotic and they didn't show you anything, then chances are there's nothing exotic to find...

    Not that that's stopped me from trying to use G25 for this purpose, of course.

    Fair enough. I definitely wasn’t expecting Japanese though. I just wanted to confirm the Southern European or Scandinavian readings in commercial tests.

    Hence why I wondered why the hell it was there and how it could be explained.

    Check my signature for my main commercial test estimates.

    It is great tool, to confirm what do you get on dna test

    I’d also like to point out that just removing random samples because you dont think they apply can often affect the remaining samples, and often tilt the results. This is obviously more common in closely related European samples but it still is something to consider. I wouldn’t take the modern calculators as serious as I would a well crafted and though fully assembled calc using ancient samples that can translate to a modern population.

    If you just wanna idea of what you are, 23 and me will get you really really close. Take a couple more if you want. If you’ve been told one thing you whole life but the tests do not reflect this, chances are high you were mislead, or whomever told you was wrong
