How does Naples compare to Sicily, culturally and genetically?

[Sikeliot]

From Dienkes' blog:


Why are you so bothered by the possibility that Sicilians might have some North African admixture? I'm of part Sicilian blood, and it doesn't bother me. Islamic rule helped to shape Sicily as it is today. That doesn't make Sicilians Arabs - they are mostly European genetically and almost entirely European phenotypically - but 6% of their ancestors are still of North African origin.

Phenotypically most Sicilians look Southeast Euro or what I call "island Med", that's not anything to be ashamed of. We are the people who civilized Europe!

Not 6% the only maghreb haplogroup in Sicily is E-M81 and it is 1,5% overall population and not all of them entered in the muslim invasion since muslims were expelled.

At this respect, the distribution of Y-chromosome haplogroup E-M81 is widely associated in literature with recent gene flows from North-Africa [49]. Besides the low frequency (1.5%) of E-M81 lineages in general observed in our SSI dataset, the typical Maghrebin core haplotype 13-14-30-24-9-11-13 [8] has been found in only two out of the five E-M81 individuals. These results, along with the negligible contribution from North-African populations revealed by the admixture-like plot analysis, suggest only a marginal impact of trans-Mediterranean gene flows on the current SSI genetic pool.

Naples (and its surroundings) is very likely mixed so you can probably find people ranging from central-Italian to Sicilian, genetically. The Campanian region as a whole is very likely transitional between Central Italians and Southern Italians.

We have not 'significant north african input'.

Sicily has almost as much NA influence as western Iberia, the highest being ~10%.

No, autosomally depends from the calculators (Dodecad is around 3-4%) but western Iberia have generally more NA influences than Sicily and also by Ydna and mtDna.
