Cosentian MyHeritage (Calabria, Southern Italy)

[Samnium]

Cosenza







Very high Sardinian and very decreased "MENA" for a Southern Italian.

Comparison with a sample from Messina :



The first sample scores no Ashkenazi Jewish neither Middle Eastern in comparison. Higher Southern Euro (without counting Ashkenazim).

Now I had guessed many months ago that maybe Cosenza had a more elevated EEF/Sardinian like component.

It's interesting because it seems this province has a lot of Greek ancestry as well, 60% Greek and South Italian.

Gedmatch?

Gedmatch?

No gedmatch unfortunately, I would try to find it

No Norman blood this time...

It´s really so difficult to separate Greek Dna and South Italian?

Yes and not, Greeks are on average more Eastern shifted and Northern shifted than Southern Italians. They are still close people, even if there are outliers that are halfway between Greeks and Levantines.

Typically a Greek from mainland would show some "Balkan" category (I don't know well MyHeritage but something like that) in addition to this category I would say.

No Norman blood this time...

I've always wondered about that honestly. I think it's not very common, and people who would have retained it are more in isolated/endogamous places.

I think it can explain the introduction of some "light" alleles (even if not all of them), in my italian family for example (I have redheads cousins but also many blue/light eyed relatives).

Other test companies do it better than MH?

At 23andme I score 10% Apulian ancestry. I have no ancestry from Italy and there was never a settlement from Apulia to Greece, especially Mainland Greece where I am from.
Apparently the algorithm reads a part of my DNA as Apulian.
The problem is even bigger for Islanders who are more Mediterranean in genetics terms and they score 20-25% Sicilian. So even if I don't trust Myheritage (23andme is much better I think) the creation category Greek and South Italian was a good move especially for Greek Islanders who are very similar to Southern Italians.

So, who influenced more in the oher genetically in your opinion, greeks in Italians or Italians in Greeks?i mean, relating it with historic population movements.

Or maybe there is not such genetic influence and only test companies algortims are still too accurate and are not able to discriminate them?


i ask also for your opinion Samnium.

About Normans. Isn't they were exclusively gentry / knights in South Italy and Sicily. What about pigmentation of modern aristocrats from this area?
