Why

Big growth rate, basically no intermarriages

They are those Ashkenazi, derived mainly from Eastern Europe?

That’s right.

I have not read it thoroughly but looks like a solid study to me.

Running RFMix on the AJ genomes with our EU and ME reference panels and summing up the lengths of all tracts assigned to each ancestry, the genome-wide ancestry was ≈53% EU and ≈47% ME, consistent with our previous estimate based on a smaller sequencing panel [9]. Our simulations suggested that the accuracy of LAI for an EU-ME admixed population is only around ≈70%, much lower than the near-perfect accuracy observed for cross-continental admixture (e.g., [29–33]). The local ancestry assignment is nevertheless non-random, and therefore, with proper accounting for errors (below), can be informative on the place and time of admixture events.

To quantitatively estimate the contribution of each subcontinental European region, we used the above-mentioned proportions of chromosomes classified to each EU region as summary statistics, and matched them to simulations in which the proportions of ancestry contributed by each region is known. Specifically, we performed 4-way admixture simulations between individuals of Levantine, Southern European, Eastern European, and Western European origin. In these simulations, we fixed the Levantine admixture proportion to 50% and varied the proportions of the different European regions. We then used a grid search to find the ancestry proportions that best fit the observed fraction of AJ chromosomes classified as each ancestry. The simulation results (Fig 2) suggest that the European component of the AJ cohort is 34% Southern EU, 8% Western EU, and 8% Eastern EU. This analysis thus suggests that roughly 70% of EU ancestry in AJ is Southern European. Using bootstrapping (S1 Text section 3), the 95% confidence interval of the Southern EU ancestry was [33,35]% and that of Eastern EU was [8,9]%. However, bootstrapping does not account for any systematic biases, which in this case are of larger magnitude (S1 Text section 3 and below).

Ashkenazi because most haredi Jews are Ashkenazi and they have 6 or 7 kid's they have kids as much as African. And migration from east europe

French-Canadians and French-Americans plot Northeast France when you'd expect them to plot Western France. Why? I'm not sure, maybe founder effect and/or genetic drift. So I think there's a good chance a future mixed Israel doesn't plot as expected.

I'm going to guess they are going to look like Central Anatolian Greeks from Cappadocia (Ashkenazi/Sephardi = Greek Islander + Mizrahi = Assyrian) (Cappadocian Greeks plot between Greek Islanders and Assyrians) with Arabian influence (Yemeni + Ethiopian). Perhaps Cypriots. The Bene Israel and Cochin Jews are a small segment of the population, I don't think they will have a big impact genetically in the long run. I could be wrong though. So my guess is they will autosomally resemble Cypriots.

italicus in Israel it is very rare for mizrahi Sephardic and Ashkenazi Jews to marry Ethiopian Jews both men and women rarely marry them SO they are gonna be more like African American. As for Yemen or they're gonna bring some arabian mixture but less then a Yemenite muslim because they have higher Levante heritage. You are also forgetting about Russian Jews who have load of Slavic and in Israel Orthodox Jews have most kids and most Orthodox are Ashkenazi

[rajputprincess]

Mizrahi Sephardic and Ashkenazi love marrying each other through. It is not even considered inter racial and most people accept these relationship

Disclaimer: this is not a political discussion and I’m not talking about the future of the country and it’s legitimacy.

Scenario: In a few hundred years- all types of Jewish people mix with eachother in a homologous way making the Israeli Jewish to plot (PCA) in a single defined place created by the mix of Mizrahim, Sephardim, Ashkenazim, Yeminite Jews, Ethiopian Jews and Indian Jews into one population.

Where do tou think the Israeli people are going to plot in this case? South levant? North levant? Between Europe and the levant? Western Asia? North Arabia?

I think in such scenario the Future Israeli Jews would be somewhat similar to Cypriots or Syrian-Lebanese people - returning to be mostly of levantine ancestry.

Between Europe and the Levant.
