DNA Testing for Jew & Muslim - YouTube[/url]
The Jews and Arab are Semite, so they are closed genetically. But turks are not Semite but Mongols origin. Dr. Oz most probably is a decendant of Jews who turned to Islam after the fall of the false prophet Shabtai Zvi. A great portion of now western Turks (Istanbul, Izmir) most probablly inharit the Jews DNA.
Jews all around the world have close DNA to each other. and close to Kurds (Eastern Syria and Turkey, North Iraq) and that shows the origin of the Jews from Mesopotamia (Abraham tale). They have close connection to Copts (Christian Egyptians which are the descendants of the real ancient Egiptians) and some tribes in Lebanon and mount Judea. But most of the now days Arabs in the Land of Israel were immigrated from Sudi Arabia and their DNA is quite different from the Northern part of the ME (Israel, Syria, Lebanon, Northern Iraq).
