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

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:





Number of Jews in Provinz Posen and West Prussia according to 1825 book:

Grand Duchy Posen ------ 70 thousand Jews
West Prussia ------------- 20 thousand Jews



^^^ And according to Karl Andree's book:

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.

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!

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.
