    Greek GEDMATCH results (ancestry from multiple greek regions )

    Using MyHeritage raw dna data.

    He also got his G25 coordinates.
    And his Y-DNA prediction from Morley Y-DNA predictor too.Though before I post it here I need someone who knows the program well to help me reconfirm it because I ran into some errors and I don't know if the final result is correct.

    PCA placements and his quite peculiar looking MyHeritage and LivingDna Ethnicity Estimate maps are also included

    His ancestry is
    From his father's side: 25% Peloponnesian from Elis, 25% Western Asian Greek from modern day Gaziemir in Turkey.

    From his mother's side: 22% Peloponnesian from Achaia, 12.5% from Sfakia region in Crete, 6.25% Western Asian Greek from Karaburun in Turkey, 6.25% from the island of Milos and the rest, 3% from around Lamia.


    (I'm terribly sorry for posting the results in this way but no matter what I do due to this being my first post I constantly get the error about posting links )

    I don't know who "he" is.

    Regardless, this is what you do:

    Copy the results. Save them to your computer.

    Go to imgur.com and download it. Go to share links. Click on third one down.

    Go to thread. Click on picture icon. Paste link. Remove the check mark.

    Post.

    I tried every combination of the links from share options on imgur with the "insert image" function ,both with and without "automatically parse links in text" checked but to no avail . I constantly get the following
    "An error has occurred lacreme! You must have 10 posts in order to post links. Your current post count is 1."

    I could have tried to accumulate the required amount of posts first but I didn't want to spam the forum with completely meaningless,for the conversation,posts on random threads .


    Thankfully Pax Augusta posted them above


    Now on to the point of the thread,
    I know that MyHeritage is...average at best but I can't understand how did they found 18,3% North/West Europe. And by feeding the raw data to LivingDna it points to it too...
    Yet on both sides of his family he doesn't have any foreign ancestry for at least 5 generations back.
    Is it due to the random nature of genetic recombination ?
    On the other hand his GEDmatch results look completely normal, if a little more southern than expected.

    As I wrote his raw data is from MyHeritage.

    While I'm trying to use Morley Y-DNA extractor I get the following during "preprocessing stage 2 of 2"
    Code:
    Your data has:
    
    • 7 Y-DNA position(s) with heterozygous calls. This may be a quirk of your autosomal DNA product. Further information is needed before these positions can be handled.
    • 80 Y-DNA position(s) lacking mutations recognised by the genetic genealogy community. These Y-DNA positions may not be very useful.
    • 1253 unrecognised position(s). Are you using data from a source other than AncestryDNA, 23andMe or MyHeritage?
    • 463 recognised mutation(s) with positive calls.
    • 1292 recognised mutation(s) with negative calls.
    • 97 recognised mutation(s) with no-calls.
    If I continue in the end I get a table with the text "This suggested classification does not account for the following positive SNPs:..." and below that a subclade prediction. Will this prediction be correct or due to the problems listed above it can also be wrong ? Is it possible that for this reason,the result may be just a placeholder ?
    I'm asking because the predicted subclade is not only rare but also intrusive to Greece.

    Relax , the results are totally normal for a greek.
    My heritage has only one reference population for Greeks, whereas Gedmatch culculators have much more that reflect the regional variation.

    Population North Sea Atlantic Baltic Eastern Euro West Med West Asian East Med Red Sea South Asian
    (pan)Greek 8.81 15.49 11.7 6.91 17.16 12.72 23.47 2.73 0.41
    Greek Central 10.06 13.12 7.23 3.39 17.29 15.74 26.95 5.24 0.16
    YOURS 10.32 10.15 6.36 5.61 19.88 17.02 26.47 2.6 1.17
    Greek Thessaly 14 11.56 11.5 5.16 17.47 12.02 22.23 4.01 1.2
    (k15 populations' avarages)

    If you use as point of reference the above chart you can see that your results match well the regional profile of Central Greece, but less the pangreek avarage.My heritage though breaks down the results by national and supra-national avarages, and as you can see you have some differences from the pan-greek avarages. My heritage matches the data with the limited number of 14-15(11 european + ashkenazi + west asian + north african and sometimes north african jewish too) reference populations they mainly use to breakdown caucasians, whereas some gedmatch calculators have probably close to 100 caucasian reference populations.So whereas Gedmatch matched you with a regional greek profile well, My heritage's algorythm couldnt and searched for a combination of admixtures that would explain your results.

    Thank you! Yeah it looks like most GEDmatch calculators are not only more accurate but also consistent on the closest populations.

    Can you help me find his Y-DNA subclade prediction ? He gets a quite rare,for Greece,subclade but for the reasons listed on my previous post (and my complete lack of understanding of how it works ) I'm not sure if it is correct
