During and following the Roman conquest of Judea, many Jews were taken captive back to Rome. uch Roman infrastructure, including the Coliseum, was built by Jewish slave labor.
So there were Jews and Italians in close proximity to one another; close enough for DNA to jump either direction. Accordingly, it is not solely a matter of Jews having Italian DNA, but also of Italians having Jewish DNA.
[And there are many blonde-haired Italians; if you see one, remember that the Vikings had occasion to sail into the Mediterranean and drop anchor in Italian ports.].
