G25 ancient model for Stears

[Defcon2]

It's only natural to get a very close fit with a lot of samples. But that doesn't indicate that some of those samples who result in the overfit contributed any real ancestry. For example in your case, it's very unlikely that you have any real North Caucasian ancestry. That's probably limited only to bordering regions in Russia and Ukraine.

This tool I do not think is useful to measure the real ancestry but its similarities in the components. For example, I usually score with the Northern Italians (Etruscans) and Illyrians but I doubt that I have real ancestry of any of them.

I didn't have such problems on 0 pen, it usually gives clean results compared to 0.25X (for example it gives me very med and very baltic samples with no in-betweeners)
If it's mixed you can give it modern name.

I actually had one such case, which was Germanic/Celtic mix and that's why I named it German, not Germanic. It wasn't clean but very modern south German like.
While Stears scored pure Germanic samples, thus his NW part is called Germanic and not German.

Hop you catch the drift

To clarify it, I say you thanks, because with your example and your little explanation with only 2 lines, it is easier to understand that method than a long technical explanation as I see in another internet sites.

Yes, because those peoples were very similar to Iberians. So you can freely count these samples to your native Iberian part.
It's different in my case since north caucasian ancestry is completely different to anything south slavic or european like, these is no genetic similarity.

So I obviously have some ancestry from Caucasus. How modern or ancient it is, that I can't tell.

You're welcome. I had no clue some other people got the same idea as me

MLN what does it mean? there should be a guide on codes and names of these samples, this looks like the encryption of Matrix.

And you know that how? My grandmother was not Croatian and she had very mixed and complex ancestry that I never learned completely about.
Since her ancestors lived in Budapest before moving to Vojvodina, they could have been mixed with anything, all kinds of people lived in that city.

I have high Kavkaz affinity on every calculator, so yeah. If I remove Kavkaz part my fits worsens considerably.

It's simply very unlikely. Your Caucasus affinity should come from an elevated CHG or Iran_N and I am sure that it falls within the spectrum for your country, even if on average you might have more of it.

Probably middle late neolithic sample, run it with moderns to see how they plot and than it will be clearer.

It's not from my Croatian part but from my mother who also scores very high CHG/west asian and she is 50% non Croatian.
My father who is pure Croat scores normally, much less than we do.

My mother's ancestry is very weird mixture of something I wasn't menage to identify yet properly.
Anyway it doesn't matter, I have Caucasus affinity and it it's there. Is it ancient or recent isn't particulary important to me.

Try these ancient components model for you and your mom. You don't need to post the results here.
If that CHG is not contained within Yamnaya, then maybe there is something interesting that happened.
I know for example that my father scores more Caucasus-related ancestry than the rest of us, but his is contained within the steppe component.
Hence, it is unlikely that it was mediated via a source from Caucasus. Maybe that's the same in your case.
