    Question 2 sisters - very different ethnicity estimates

    2 sister (50 % of shared DNA) made FTDNA FamilyFinder test and the data I uploaded to MyHeritage and DNA.LAND. Their results are very differerent, especially Ashkenazi percentage, Balkan and others. Here are the results:

    FTDNA MyOrigins:
    Sister A: Sister B:

    MyHeritage
    Sister A: Sister B:

    DNA.LAND:
    Sister A: Sister B:

    Ashkenazi percetage (FTDNA - MH - DNA.LAND)
    Sister A: 8 - 17.2 - 0 %
    Sister B: 6 - 12.6 - 7.7 %

    Balkan percentage:
    Sister A: 11 - 45.9 - 11 %
    Sister B: 3 - 59.1 - 0 %

    Northwest European percentage (FTDNA West and Central/Scandinavia)
    Sister A: 6/0 - 21.3 - 23
    Sister B: 3/0 - 9.8 - 7.3

    East European (Slavic)
    Sister A: 70 - 15.6 - 36
    Sister B: 89 - 18.5 - 50

    etc.

    What could be the reason for so big differences between two sisters and among the tests?

    They are not so much different.
    Give us some gedmatch results.

    I agree they're not so different. In any case most of these tests will only give you the broad brush strokes. They're not that reliable. Plus, don't forget the sisters will only share about 50 percent of their DNA in common.
    Living DNA's former Cautious mode:
    Wales-related ancestry: 86.8%
    Cornwall: 8%
    North England-related ancestry: 5.2%
    Y line: Peak District, England. Big Y match: Scania, Sweden; TMRCA 1,250 ybp (YFull);
    mtDNA: traces to Glamorgan, Wales
    Mother's Y: traces to Llanvair Discoed, Wales

    1. It's perfectly fine for siblings to have different results, just as having different eye colour, nose shape, height or any other phenotypical differences, especially if their parents come from genetically different and/or diverse backgrounds.

    2. I reccomed to always go first with results of company you sent your dna to, as companies have different algorythms and refferenc groups, it can be compared to transimtting from metric to imperial system - you know that pint is a bit bigger than half a liter, and if you buy a pint you'll get about the same, but not exactly the same.

    Siblings can vary quite a bit, I share a lot of results of both myself and one of my brothers and there are differences although overall you can tell we are from the same family.

    I know that siblings has just 50 % of DNA in common but the results of various tests looked too different to me.

    Here are the Eurogenes results. Admix Results are not so different, but in Oracle-4 is big difference. And even bigger difference to reality - their grandparents ancestry is Czech - Czech - Czech - Hungarian, backed by long family tree.
