My DNA Haplogroup J1 :) The time of origin of haplogroup J1 is 15,000 to 24,000 years ago on the Arabian Plate. Highest frequencies in Semites and Dagestanis. The frequency of haplogroup J1 collapses suddenly at the borders of Arabic speaking countries and Daghestan with other countries, such as Iran (10.5%) and Turkey (9%). The distribution of J1 outside of the Middle East may be associated with the Semites who traded and conquered in Sicily, southern Italy, Spain and Pakistan. In general J1 has a very low frequency in Europe. However, higher frequencies has been reported in the central Adriatic regions of Italy Gargano (17.2%), Pescara (15%), in the Mediterranean (11.1%), South Sicilian (10.7%), Crete (8.3%), Malta (7.8%), Cyprus (6.2%), Greece (5.3%). In North Africa, J1 first entered Ethiopia with the spread of Semitic speakers in Eritrea (11%), Ethiopia (9%), Ethiopia-Amhara (33.3%). It spread later to North Africa in historic times; Algerians 35.0%, Tunisians 31%), where it became something like a marker of the Semitic expansion in the early medieval period. J1 also may be found with high frequency in the northern parts of Sudan: Arabs 45%, 41%, Copts 39%, Beja 36%), and present with lower frequency in the region of Darfur: Masalit 6%, 6%). Haplogroup J1 may be found in as many as 20% of Egyptian males, with the frequency of this haplogroup tending to be comparatively high in the south of the country. Haplogroup J1, defined by the 267 marker is most frequent in Yemen(76%), Saudi (64%) Qatar (58%). J1 is generally frequent amongst Negev Bedouins (62%). It is also very common among other Arabs such as those of the Levant, i.e. Palestinian (38.4%), Syria (30%), Lebanon (25%), In Jewish populations, J1 constitutes 30% of the Yemenite Jews, 20.0% of the Ashkenazim results and 12% of the Sephardic results.
