T is a very rare paternal haplogroup....it is found in highest frequencies in Jordan,Egypt,Iraq and parts of Iran....found in lower frequencies among Turks, armenians....in Europe it peaks near the Aegean Sea off of islands like Chios and near Crete and also across Italy, Spain and Portugal is a 2-6% average in those more Mediterranean regions I would say. The Horn of Africa (Eritrea,Somalis,Ethiopia) actually has a considerable high. It can also be found in 5-15% of Egyptian lines and 15-20% of Jordanian lines and about 10-15% of Iraqi lines, 10-13% of Assyrian lines towards Anatolia....several cities across Iran have interesting frequencies 12-15% range which is a global high. Portuguese Jews have 15% T, and so do Kurdish and Iraqi Jews.....Iranian Jews also have 14%. It is present in 12% of Palestinian males 10% of Armenians but is rarer in Syria and Lebanon. It seems to be barely present in Ashkenazi Jews, or Jews from Israel though oddly. Among all Jews it is most prevalent in the mizrahim Jews of the Iraq/Iran regions.
