[QUOTE]Originally posted by Firewall: [QB] Y-DNA of Sephardi Jews The term "Sephardi" refers to significantly different populations from one study to another. It can have a very restrictive meaning and only referring to people speaking Judeo-Spanish (excluding Moroccan Jews) or at the opposite the term Sephardi may designate all non-Ashkenazi populations (excluding Jews from Ethiopia, Yemen and the Kurdish Jews). Between these two extremes, all kinds of variations exist. Investigations made by Nebel et al.[2] on the genetic relationships among Ashkenazi Jews, Kurdish and Sephardi (North Africa, Turkey, Iberian Peninsula, Iraq and Syria) indicate that Jews are more genetically similar to groups in northern Fertile Crescent (Kurds, Turks and Armenians) than to Arabs. Considering the timing of this origin, the study found that "the common genetic Middle Eastern background (of Jewish populations ) predates the ethnogenesis in the region and concludes that the Y chromosome pool of Jews is an integral part of the genetic landscape of Middle East. Y-DNA of Jews from North Africa The largest study to date on the Jews of North Africa has been led by Gerard Lucotte et al. in 2003.[30] This study showed that the Jews of North Africa[Note 7] showed frequencies of their paternal haplotypes almost equal to those of the Lebanese and Palestinian non-Jews. The authors also compared the distribution of haplotypes of Jews from North Africa with Sephardi Jews and Ashkenazi Jews and found a common origin between these groups.[38] The Jewish community of the island of Djerba in Tunisia is of special interest, making the tradition back to the time of the destruction of the First Temple. Two studies have attempted to test this hypothesis first by G. Lucotte et al. from 1993,[39] the second of F. Manni et al. of 2005.[40] They also conclude that the Jews of Djerba's paternal gene pool is different from the Arabs and Berbers of the island. For the first 77.5% of samples tested are of haplotype VIII (probably similar to the J haplogroup according Lucotte), the second shows that 100% of the samples are of Haplogroup J *. The second suggests that it is unlikely that the majority of this community comes from an ancient colonization of the island while for Lucotte it is unclear whether this high frequency is really an ancient relationship. These studies therefore suggest that the paternal lineage of North African Jews comes predominantly from the Middle East with a minority contribution of African lineages, probably Berbers. Y-DNA of Portuguese Jews A recent study by Inês Nogueiro et al. (July 2009) on the Jews of north-eastern Portugal (region of Trás-os-Montes) showed that their paternal lines consisted of 35.2% lineages more typical of Europe (R : 31.7%, I : 3.5% ), and 37% lineages more typical of the Near East (J1: 12%, J2-M172: 25% ) and consequently, the Portuguese Jews of this region were genetically closer to other Jewish populations than to Portuguese non-Jews. Y-DNA of Oriental Jews Lucotte et al. 2003 study found that (Oriental, Sephardic, Ashkenazic Jews and Lebanese and Palestinians), "seem to be similar in their Y-haplotype patterns, both with regard to the haplotype distributions and the ancestral haplotype VIII frequencies." The authors stated in their findings that these results confirm similarities in the Y-haplotype frequencies of this Near-Eastern populations, sharing a common geographic origin." Y-DNA of Roman Jews The Roman Jews are as their name suggests Jews were distinguished as originating in the Middle East. Mr. Hammer et al. show their paternal lines are close to those of Ashkenazi Jews, mostly originating from Middle East. Y-DNA of Kurdish Jews In the article by Nebel et al. the authors show that Kurdish and Sephardi Jews have paternal genetic heritage indistinguishable. The study shows that mixtures between Kurdish Jews and their Muslim hosts are negligible and that Kurdish Jews are closer to other Jewish groups than to their long term host population. Mr. Hammer had already shown the strong correlation between the genetic heritage of Jews from North Africa with Kurdish Jews. Y-DNA of the Jews of Yemen The studies of Shen and Hammer et al. show that the paternal genes of Yemenite Jews is similar to that of other Jewish populations. [/QB][/QUOTE]
