East European and Slavic signatures in the Italian genome.

These are the Y-dna based haplogroups which can be linked to Slavic or Balkanic admixture from most likely East European delivered populations. Posted by an user from an other website:

Personally, I don't think ancient Greeks carried significant amount of "Slavic" admixture, at least far less than modern Greeks. We already know the genetic background of some Griko speaking communities who have been isolated and relatively lack the Continental-Steppe like ancestry which is a characteristic for East and Northwestern European admixture (can be some ancient Indo-European link as well) These are just guessings but It has a great chance that these Y-dna characteristics been brought directly by Slavic speaking populations not by groups which mixed with Slavs then migrated to Italy (Aberesche belong to the exceptiong, but they were already a mixed population as they left Albania in the 16-17th century, because Slavic tribes been migrating to the balkans for 1000 years before the Aberesche migrations)

Wikipedia states the possibility that some Slavic settlements could have been brought to Italy during the Byzantine era where merchants brought Slavic slaves.

Saqāliba (Arabic: صقالبة, sg. Siqlabi) refers to Slavic slaves, kidnapped from the coasts of Europe or in wars, as well as mercenaries in the medieval Muslim world, in the Middle East, North Africa, Sicily and Al-Andalus. It is generally thought that the Arabic term is a Byzantine loanword: saqlab, siklab, saqlabi etc. is a corruption of Greek Sklavinoi meaning Slavs (from which the English word slave is also derived.^[1] The word is often misused to refer only to slaves from Central and Eastern Europe,^[2] but it refers to all Eastern Europeans and others traded by the Arab traders during the war or peace periods.^[3]
There were several major routes of the trade of Slav slaves into the Muslim world: through Central Asia (Mongols, Tatars, Khazars, etc.); through the Mediterranean (Byzantium); through Central and Western Europe to Al-Andalus. The Volga trade route and other European routes, according to Ibrahim ibn Jakub, were serviced by Radanite Jewish merchants. Theophanes mentions that the Umayyad caliph Muawiyah I settled a whole army of 5,000 Slavic mercenaries in Syria in the 660s.

Italianized Croat for sure. Rovigno (Rovinj) is a city in Croatia with strong Italian influences.
