Davidski neolithic G25 admixture with Jewish G-Grandparent

[Hawthorn_Grove]

Hi all,

Popped this as a reply in the other thread about Davidski's neolithic calculator but thought I'd start a new thread to see if I can garner any views.

These are my G25 results on that calculator:

Target: Hawthorn_Grove_scaled
Distance: 3.6685% / 0.03668480

45.4 Yamnaya_RUS_Samara
41.6 TUR_Barcin_N
13.0 WHG

I'm interested in whether this admixture would be expected with one Jewish Great Grandparent, or whether it's unlikely not to see some element of Levant_PPNB or other non-european source.

Appreciate any responses.

Do you have one jewish g-grandparent?

This demonstrates what G25 is and how it differs from saliva test results.

Yes, that's right. But no middle-eastern signal or ancient DNA matches.

Indeed, though it's odd because modelling a sample like Ashkenazi_Lithuania shows admixture from the Levant and modern-day Iran.

It seems to me that commercial testing companies identifying "European Jewish" are hiding a lot of potential differences underneath.

Share me your g25 data.
Do you know your genealogy?

I have PMed it to you.

My genealogy is 6/8 English, 1/8 Scottish and 1/8 Jewish supposedly from Ukraine.

I don't think they're doing it right at all either, but at least there's the potential for it to happen in the future.

Post your Euro K13 results from GED, we'll see if you score an elevated amount of East Med. 1/8 is not a lot if you keep in mind that Ashkenazi Jews are already nearly half European.

Yep, you do score more East Med than most White British people would

It just can't be more evident. 5.6% Lebanese is pretty much 1/8 Ashkenazi. Case closed. :)

[Hawthorn_Grove]

Very useful, thank you. I suppose my question is, why does that not appear in G25 when using Neolithic samples which include the levant?

[Leto]

I don't know. Maybe because the amount of Jewish blood in you is just too small, so that simply got sucked into other components. This is what the Ukrainian Jewish average looks like

Target: Ashkenazi_Ukraine
Distance: 0.0192% / 0.01919395
57.2 TUR_Tepecik_Ciftlik_N

4.2 IRN_Ganj_Dareh_N
2.7 MAR_Taforalt
1.5 Han
0.6 WHG

As you can see, it's only 7.4 percent Levant PPNB.

Gedmatch is still useful and sometimes even better than G25, even if some people snub it as outdated. They just don't know how to use it properly.

[Hawthorn_Grove]

Thank you for the analysis, that’s really helpful.
