Why does my grandfather's brother score 4% MENA on GEDmatch but 0% Jewish on FTDNA?

[Peterski]

His K36 results show that he has around 4% of MENA admixtures in total:

Arabian 1.85 Pct
Basque 1.09 Pct
Central_Euro 4.42 Pct
East_Balkan 3.68 Pct
East_Central_Euro 25.90 Pct
Eastern_Euro 13.62 Pct
Fennoscandian 12.41 Pct
French 4.95 Pct
Iberian 6.29 Pct
Italian 2.92 Pct
Near_Eastern 2.00 Pct
North_Atlantic 5.76 Pct
North_Caucasian 1.75 Pct
North_Sea 13.11 Pct
Omotic 0.07 Pct
Volga-Ural 0.18 Pct

But his Family Finder MyOrigins show 0% Jewish, instead 29% Balkan:

His surname Meller which is common in formerly Prussian areas of Poland:
(in 1890, this surname correlated with ethnically Polish areas of Prussia)

But Meller is also common in Israel today, meaning some Jews have it too:

Prussian Poland in addition to Poles and Germans, had many Jews as welll:

Jews in the Kingdom of Prussia by region in 1817 (highest in Provinz Posen):

Grand Duchy Posen ------------------- 52,568
West Prussia --------------------------- 12,632
Silesia ---------------------------------- 16,476
East Prussia ----------------------------- 2,389
Pomerania ------------------------------ 2,976

Provinz Sachsen ------------------------ 3,242
Westphalia ------------------------------ 9,723
Jülich-Cleves-Berg ---------------------- 8,372
Grand Duchy Niederrhein ------------- 10,469

TOTAL --- 127,345 (ca. 1.21% out of 10,536,571 inhabitants)

According to Georg Hassel in 1819 Posen and West Prussia had 61,400 Jews:

Not really an answer to your question but how many cMs do you share with him on GEDmatch? I'm very curious.

[JosephK]

Because none of these things are very accurate?

[Leto]

His K36 results show that he has around 4% of MENA admixtures in total:

And East Med+Red Sea from K13/15?

Ftdna is funny. Probably it got sucked into southeast europe. When i uploaded 23andme file into frdna my origins my 10% asia minor went down to 3% and 11% sephardic disappeared and my southeast europe rose from 13% to 36% (lol 36% southeast europe for an Uzbeki)

[Peterski]

Ftdna is funny. Probably it got sucked into southeast europe.

I've uploaded his raw data to DNA Land, here are the results:

They claim 13% AJ:

But weirdly enough, his high Balkan score did not disappear.

I think Y-DNA test will show whether his lineage is Jewish.

[Peterski]

David's model in Global25 gives him 4% Ashkenazi and some Germanic, Eurogenes JTest Oracle detects his Jewish too:

73.2% Polish
20.6% Lithuanian
3.8% Ashkenazi_Jew
2.4% German

But his Y-DNA is Balto-Slavic R1a (so Jewish and Germanic admixtures are not associated with his direct paternal line):

Shalom!

[Smitty]

None of that is reliable in my opinion. You scored none on 23andme, which people agree is the most reliable with regard to Ashkenazi ancestry. I don't think you're part Jewish.

I score no MENA admixtures on GEDmatch. He does. I'm not part Jewish, but grandfather was judging by these results. These segments were simply lost in genetic recombination.

[Smitty]

I score no MENA on GEDmatch too. I'm not part Jewish. But grandfather was judging by these results. These segments were lost in genetic recombination.

Nah, it's a tiny amount, and on GEDmatch, what's more. I bet a lot of fully North European people would score similar amounts.

4% is way too much to be noise. North Europeans don't score such admixtures unless they have some recent MENA/Jewish anestry.

Probably your grandfather is not your grandfather.

[Peterski]

Probably your grandfather is not your grandfather.

He is, I match with his brother (long shared DNA segments).

Remember that people inherit only ca. 1/4 from grandparent.

[Cristiano viejo]

He is, I match with his brother (shared DNA segments).

How is possible that he being 4% MENA you dont score that component then?

[Peterski]

I inherited other parts of his DNA, not this specific part.

[Cristiano viejo]

Is this even possible? i find this interesting but a bit scifi. If this was true, genetic means nothing, less than crap, since what matters about genetic if you can not know your real ancestry then? people like you, with 0% MENA, will think dont have MENA ancestors but in reality they could have :noidea:

[Pater Patota]

I get 85% Middle Eastern(82%Asia Minor&3%Sephardic Jew)on FTDNA, I get 6% Ashkenazi on Jtest but I have zero Jewish match and zero Jewish ancestry as far as I know.

You've been here for 7 years and almost have 30k posts, but this baffles you? Are you retarded?

You are the retarded for thinking I have been here to learn about genetic.

6% on the JTEst may be normal for your ethnicity. Check the spreadsheet.
