Genetica d'Italia

[trebil]

It’s true but at this point better than nothing.

I have professional studies that I can post here by the way.

Ok, we know all those studies, you wouldn't say anything new

I have very local studies about Calabrian genetics/population that I posted on others threads, not known at all.

I’m not talking about Fiorito et al. etc.

Is this model based on unscaled or scaled G25?

[kaltar]

Celtíbero Itálico, there is something wrong both in your model and in your results, are you mixing by chance unscaled and scaled samples?

[Rocinante]

Is this model based on unscaled or scaled G25?

No, the model was right, but i edited it because there was a mesolithic england sample that was giving strange results to northern europeans by giving them very low WHG related ancestry, now is good.

Is unscaled, look at the distances now.

The results in your model for Italians are unreliable. The peak of EEF farmer ancestry according to your model is in Italian Jews, while actually it is in northern Italians. Yamnaya is often inflated (just few examples: Sicilians East with 41.2% Yamnaya at 0.25, Italian_Aosta_Valley over 56%!). Very unlikely this big difference between Abruzzo and Molise.

Distances do not prove the correctness of a model. There is a reason why most models are based on scaled samples. The problems may also be due to the lack of accuracy of the G25 unscaled datasheets.


Some of them are not even real ancestral components, like KEN_Pastoral_N.

[kaltar]

Problems also with Greek samples if one uses your model. Greek_Thrace with 57.8% Yamnaya! C'mon.

Yeah i know, i'm realizing it has some problems, spanish references are getting weird results too. I will make a new one, but scaled.

[kaltar]

And problems as well as many Spanish averages.

Spanish_Asturias, Spanish_Barcelones, Spanish_Castilla_Y_Leon Spanish_Andalucia with more than 50% of Yamnaya!

These results are not at all plausible.
