The Phonecians were probably Haplogroup J2 - see
http://en.wikipedia.org/wiki/Haplogroup_J2_(Y-DNA)
"In Europe, the frequency of Haplogroup J2 drops dramatically as one moves northward away from the Mediterranean. In Italy, J2 is found with regional frequencies ranging between 9% and 36%.[16] In Greece, it is found with regional frequencies ranging between 10% and 48%. Approximately 24% of Turkish men are J2 according to a recent study,[18] with regional frequencies ranging between 13% and 40%.[5] Combined with J1, up to half of the Turkish population belongs to Haplogroup J.
It has been proposed that haplogroup subclade J2a-M410 was linked to populations on ancient Crete by examining the relationship between Anatolian, Cretan, and Greek populations from around early Neolithic sites.Haplogroup J2b-M12 was associated with Neolithic Greece (ca. 8500 - 4300 BCE) and was reported to be found in modern Crete (3.1%) and mainland Greece (Macedonia 7.0%, Thessaly 8.8%, Argolis 1.8%).[33]
Sephardic Jews have about 29% of haplogroup J2[1] and Ashkenazi Jews have 23% or 19%."
However to properly look at Jewish ancestry one should really look at the maternal mtDNA as the jews work on a female line of descent.
