Admixture chart for South Europeans from the Guanche study -- Italians, Greeks, Spanish highlighted

[Sikeliot]

I have isolated this for all to see. It is an admixture chart.

Coriell and Comas for the Greeks refer to either an institution or study that provided the samples, NOT a region of Greece.

Of the colored components:

Purple = Caucasus
Dark Green = Levant
Aqua Green = North Africa
Black = Sardinia
Dark Pink = Basque
Light pink = Balto-Slavic

Iberians and, to a lesser extent, the Italians have more of the Basque component than the Greeks, but less of the Balto-Slavic, but both Italians and Greeks have more Caucasian than Iberians. Unsurprisingly, western Sicily has the most of the green Levantine component, and is the only Italian region with visible North African, which the other Italians and Greeks lack.

Here is Cyprus.. basically it ls like Sicily but without the North and West European.

Very good :popcorn:

[Raizen]

Why iberians score Balto-Slavic?

[Sikeliot]

Aragon, Basque Country, and Valencia have no North African. Interesting.

And I was right, the stronger MENA signal is western Sicily.

My question is for the Levantine part. For the sicilians who score high east med and Levantine where does this come from? The Phoenicians? Jews? Syrians? In gedmatch that is my highest amounts. Would love to know where that part comes from?

Do you know maybe what Greek sample is in Lazaridis 2016

GREEKGRALPOP

I'm currently uploading some genome from this study to gedmatch. But there is no point to upload such reference if it isn't regional.

All I know is it is from the mainland.

Bronze Age migrations plus later influences like Phoenicians, Jews, etc.

Why iberians score Balto-Slavic?

It's balto-slavic like admixture. Not balto-slavic as some who don't fully understand this stuff would claim.

So it came with the Indo-Europeans?

Might have and probably did. Everyone in Europe has some balto-slavic admixture depending on what kind of admixture you use to model populations.

They are using the usual academic samples (used in many calculators and papers), so the results are almost the same.

There is also Greek WGA. Who are they? That grey component peaks in BedouinB.

I have absolutely no idea. I didn't post it for this reason. I assumed it was Mycenaeans. :lol:

[RN97]

You also didn't link the study and you should have explained what the yellowish brown means.

According to this, GREEKGRALPOP = Greek Comas.

It's a sample from Thessaloniki, Macedonia.

Found, it's a sample from Athens, Central Greece, according to this.

This explains the high Balto-Slavic component -- the light pink.

Here is the study:

And orange component peaks in Druze. The green one on the other hand peaks in Arab Levantines.

What do you make of the differences within Italy? I think it makes sense the MENA elements are higher in western versus eastern Sicily/Greece, but the Caucasus input is roughly constant across all of these.

We clearly see Spanish people differ the most out of Tuscan, southern Italian, Greek, and Spanish.

Interesting how much they differ.

Where in Sicily are east and west Sicily samples from? Does it indicate?

[Sikeliot]

Gray component must be of Near Eastern origin because it replaces the green one.

South Italian from Belvedere, Cosenza, Calabria.

East Sicilian from Siracusa, Sicily.

West Sicilian from Trapani, Sicily.

Yes, Gray component in Greek WGA is just another type of Near Eastern-like component.

Part of these Near Eastern-like components could be some kind of Natufian, also most Iberians have it.

[Wrong]

Gray is an Ancient component of Enlightened Early Farmers. It diluted over time. ;)

[Sikeliot]

South Italian from Belvedere, Cosenza, Calabria.

East Sicilian from Siracusa, Sicily.

West Sicilian from Trapani, Sicily.

Syracuse is the least Near Eastern region of Sicily. Trapani is actually less so than is Messina, Catania, Palermo, Agrigento or Caltanissetta, so these samples actually might understate that green component for Sicily. Syracuse would have the least of every province.

It's balto-slavic like admixture. Not balto-slavic as some who don't fully understand this stuff would claim.

It's simply WHG-SHG, they are usually grouped together in admixture, not particularly Balto-Slavic (ofc it's high there)

The full K2-K15 run is in page 4 of the pdf (the charts are inverted left to right, it's an error)

Where did 'NW-European' get transferred into under your chart? Becuz on my chart here below they DO have a NW-Euro category..perhaps it had gone under the 'Basque' component??...:

Aragon, Basque Country, and Valencia have no North African. Interesting.

That has to be off for Valencia and Aragon but especially Valencia.

There s no really NW component, but it would be a mix of dark pink, light pink and black, something like that if NW is Kent for example or Orcadian like in yours. As you raise the K things get broken down that are not necessarily that different, when you reach really high K, like 10 and more, they just branch out as new very specific elements. This is why admixture is always more meaningful seen in a complete range of K than just one, so yes the dark pink is also made of other things you see at lower k, mostly some light pink and black, which is in itself like 2/3 light pink (WHG-SHG) and 1/3 purple (basal-ish), etc...
The end goal is to characterize the Guanches there, you need other populations to compare but the focus isn't on the NW or anything like that in the runs.

Valencia has some little cyan on two samples just seems lower than usual, Aragon i don't remember seeing them scoring any in other tests, this is really where it starts to fade to nothing as you get closer to the heavily Basque areas.

Aragón is not the only area closer to Vascongadas :whistle:
In fact historically Castilla was closer to Vascongadas than Aragón was.

[Sikeliot]

I wish they would use Palermo and Catania for east/west Sicily because Trapani and Syracuse both understate the Near Eastern components (especially Syracuse which is the least Near Eastern province). But maybe this is intentional :lol:
