Jews 31% R1b??

[Longbowman]

Sephardic jews do have significant R1b(around 25% or 1/4 of portuguese Jews) from assimilated goyim iberians

Belmonte Jews are not genetically similar to other Sephardim. They have extremely high levels of Iberian admixture. This is true of most converso families/populations. They are very unique and there are only 250-400 of them.

I myself am [distantly] Belmonte Jewish, btw.

Yeah, but the original Dutch Jews were very much Sephardic refugees. as were the original (second wave) English Jews, post ECW. There wasn't much back-migration of Eastern European Ashkenazi into Western Europe until around the late 18th century.

But this is almost completely irrelevant to modern Dutch Jewish genetics, which is the subject at hand. Most Dutch Ashkenazim are not from Eastern Europe, but from Germany. There are plenty of indigenous Ashkenazi communities in Western Europe.

Your source is bizarre, most data suggests total R for Ashkenazim is about 18-20%, mostly R1a. I have never seen R1b reported so highly in any subgroup, not even Dutch Ashkenazim (which do score higher than other Jews wrt R1b).

Is the R1a mostly from Poles or somewhere else?

Whilst that is intuitive and I'm sure it's a contributing factor, Pines can go on for a while about how it's apparently probably MENA.

I don't see where R1a is or was any higher than anecdotical in MENA. Unless we are talking about a very old basal subclade or some enormous founder effect.

It's almost all one clade. Impossible to be Polish. It's ultimately Iranic and inside R-CTS6.

This is the broader clade: https://www.yfull.com/tree/R-CTS6/
This is the Ashkenazi clade inside of it: https://www.yfull.com/tree/R-Y2619/

It has been discussed to death. Only question is when and where this Iranic person became Jewish.

[SUPREEEEEME]

Around 93% of Ashkenazi R1a (keeping in mind R1a is 8.9% of Ashkenazim) falls under R-Y2619, which in turn falls under R-CTS6 - which is a MENA clade. The closest relations to this Levite branch are in Western Iran, Northern Iraq, and Eastern Anatolia. So we can assume the line came from there at some point. So it's definitely MENA, and certainly not Eastern European.

I don't see where R1a is or was any higher than anecdotical in MENA.

Iranic-speaking peoples have R1a-Z93. Turkic too.

Yeah. Whereas R1b seems mostly Euro except R1b-V88.

[Tongio]

Yeah. Whereas R1b seems mostly Euro except R1b-V88.

Yeah that is why here in Brazil if you are of colonial portugueses origin and your paternal ancestor was a converso he wont nescessarily be J, significant chance of being R1b. I dont know if Belmonte jews were that atypical for portuguese jews , those were heavily integrated compared to other parts of europe and mixing happened in both directions in most parts of Portugal not just Belmonte probably.

Well, they were atypical, we have DNA results from other Sephardic communities to demonstrate it.
