  • Question re Jewish subpopulations specificity on gedmatch eurogenes K15/K13

    Hello. I am very new to all of this but already fascinated. I tried my best to get a handle on the concepts behind the eurogenes calculator but I am still left with a question too difficult to answer myself and would truly appreciate any input those on this forum who are far far more knowledgable and experienced could provide.

    At this time I still have FTDNA FamilyFinder, Y-111, and mito sequence pending. But a few days ago my ancestryDNA results returned and to no surprise they came back as 98% European Jewish. Minor surprise was subcategory of European Jewish isolated to Western and Central Europe, but no Central and Eastern under their European Jewish ethnicity. Somewhat more of a surprise was my remaining 2% trace came back Middle East as I was expecting more eastern or northern european admixture over a couple millenia. I uploaded the raw data to Gedmatch.

    To best of my knowledge and confidence I trace my great grandparental lines to births in modern day Czech Rep, Ukraine, Belarus, and Poland. A few additional lines were Prussian, though further east in Sroda which is now Poland. Persecution events brought these lines together outside of Europe. I think of these locations as Central Europe bordering on Eastern Europe origins but my DNA results seem a touch off from that.

    My ashkenaz value on the JTest is 28.63. My East Euro on JTest is zero. My Middle East, East Medit, and Atlantic are each a touch higher than the benchmark AJ, and AJ gives me a distance of 5.03 which it seems on other boards or threads is high and I've read a good fit is something at or below 2.

    # Population Percent
    1 ASHKENAZI 28.63
    2 EAST_MED 21.8
    3 MIDDLE_EASTERN 11.02
    4 WEST_MED 10.91
    5 ATLANTIC 9.25
    6 WEST_ASIAN 7.08
    7 NORTH-CENTRAL_EURO 6
    8 SOUTH_BALTIC 3.73
    9 EAST_ASIAN 1.59

    Single Population Sharing:

    # Population (source) Distance
    1 AJ 5.03
    2 South_Italian_&_Sicilian 21.32
    3 GR 23.17
    4 Tuscan 25.26

    So I wanted to see how I can get closer to 2 and have run different simulations in Gedmatch. Below I will post my K13 and K15 runs and what I want to ask this board for guidance is whether the K15 which includes a Sephardi benchmark population in my Oracle simulations which provide a better result than Ashkenazi or the K13 run with 50/50 Ashkenaz/Sephardi split truly holds any weight? The 50/50 splits in both K13 and K15 tests give a distance closer to 3 which is better than the 5 of AJ alone on the Jtest. Should I now be wondering if there may be some admixture of a different Jewish line like Sephardi in the past?

    I am now even more curious what my Y and mitochondria haplotypes will be.

    For East European DNA affinities, you will want to look at your Eurogenes K36 scores for Central European, East-Central European, East European, Fennoscandian, and Volga-Ural. You do have suggestions of having some SOUTH_BALTIC by Eurogenes' Jtest and that stands for DNA that is very common in the Poland-Lithuania region. K36 will show the full amount of DNA from that region without any of it being subsumed by an Ashkenazic category.

    You certainly could have some Sephardic ancestors. The first step should be to look in the lower reaches of your Family Finder match list for any people who are members of such communities as: Mexican, Costa Rican, Puerto Rican, Cuban, Portuguese, Spanish, Syrian Jewish, Turkish Jewish, Moroccan Jewish, and similar.

      Along those lines, another observation I have is that your 7.63% Baltic estimate in Eurogenes K13 reflects East European DNA. So you certainly do have some.

        Eurogenes K36 run

        Thank you so very much for that advice. Below is my K36 run. A little in the East Central Euro, some trace in the Eastern Euro and very trace in the Fennoscandian. So that would be 2.21% Eastern European consumed by the AJ category in the JTest? Would this change the conclusion of the K15 oracle?

        Yes I would have expected my return to have been nearly as solid Polish region Ashkenaz as the test could get since about 50% of my great grandparents would have been born in areas that are modern day Poland. The others in Belarus, Russia, and Moravia. I was just surprised when the K15 oracles were giving me those leans toward Sephardi population and wondered if any of my ancestral lines were mid or late diaspora emigrations from a mediterranean population into the classic 'Ashkenazi' geographic region.

        I am still waiting for this company's FamilyFinder run to post and hope the interface will allow more fine delving such as that into my matches to look for Spanish and Latin surnames. I have some 13680 cousin matches on ancestry and it's overwhelming to the point where looking for anything or anyone is like a needle in a haystack. A good number of the entries are also initials or handles to hide their identity and they don't have a tree or locked access to their tree. Nonetheless I have been looking for surnames like that and finding a very scattered few and starring them. Still I'm not sure if those are just people with Spanish surnames and an Ashkenaz married into their line.

          Brief point

          I guess taking a step back a more simple question is whether my results with the slight further tilt toward mediterranean and middle east are even something that would be considered uncharacteristic for an Ashkenaz? Or could it still be in the expected zone so to say?

            csb461, the elements you're showing are typical of Ashkenazim and the amounts are within the normal ranges of variation.

            Your amount of Slavic DNA (actually not 2.21% but only 2.11% adding up the Central Euro + East Central Euro + Eastern Euro + Fennoscandian + Volga-Ural elements) is quite low in comparison to some other Ashkenazim such as my parents and I. My total of those 5 elements is 8.86%. But there are many other Ashkenazim who have low Slavic DNA amounts.

            Another difference is you have a small amount of East Asian DNA (0.24% East Asian + 0.54% Indo-Chinese + 0% South Chinese in Eurogenes K36; 1.59% in Jtest) whereas I have none.

            You do have more Middle Eastern DNA in Eurogenes K36 than I do:
            Arabian: 7.08% for you vs. 3.87% for me
            Armenian: 5.16% for you vs. 5.67% for me
            East Mediterranean: 13.66% for you vs. 10.64% for me
            Near Eastern: 15.73% for you vs. 15.42% for me
            West Caucasian: 5.76% for you vs. 4.23% for me

            I have only 2.18% North African compared to your 4.39%.

            My South Central Asian score of 2.50% is not that common among Ashkenazim.

            I just realized that you tested so recently that your AncestryDNA chip is the new v2 chip rather than the v1 chip. Because v2 is only partially compatible with Family Finder, you will not be able to view your lower-level matches within Family Finder, e.g. Latin Americans, but such matches will still be findable inside GEDmatch.

              Agree with Khazaria. It should be noted that although there is a common Ashkenazi pattern, there is great variation around the center. For example, some calculators show individual Ashkenazis to be closer to Sicilians than to other Ashkenazis.
