About us

1-(J1) Haplogroup is believed to have been generated some 10,000 years ago south of the Levant and in the heart of the Arabian Peninsula (Source is National Geographic Genetic Project)

2-(J1) Haplogroup is very common in Arabs and Jews (about 65% of Bedouins) and (almost half of national geographic data base J1 persons are Jew) (source is Semino et al.: Origin, Diffusion, and Differentiation of Y-chromosome Haplogroups E and J: Inferences on the Neolithization of Europe and Later Migratory Events in the Mediterranean Area) and (National Geographic Genetic Project).

3-Research shows that (J1) haplogroup makes about 72% of Yemen people, 34% of UAE people, 58% of Qatari people, 50% of Iraq people, 55% of Palestinian Arabs, 48% of Oman People, 34% of Tunisian, and 35% of Algerian. Rest of these countries populations is a mixture of other Haplogroups. (Source: Y-chromosome diversity characterizes the Gulf of Oman by Cadenas et al. 2008) and (Semino et al. : Origin, Diffusion, and Differentiation of Y-Chromosome Haplogroups E and J: Inferences on the Neolithization of Europe and Later Migratory Events in the Mediterranean Area) and (The Levant Versus the Horn of Africa by J.R Luis et al 2004).

4-All persons who carry J* haplogroup (because of not belonging to J2) were considered as members of (J1) haplogroup by Cruciani et al. (2002), Nebel et al. (2001), and Bosch et al.(2001). (Source is Semino et al. : Origin, Diffusion, and Differentiation of Y-Chromosome Haplogroups E and J: Inferences on the Neolithization of Europe and Later Migratory Events in the Mediterranean Area).

5-(J1) haplogroup had expanded to the rest of the world all over history but distinctively during two main periods. It had expanded out from the Fertile Crescent about 7000-9000 years ago during the Neolithic times (last part of the stone age). The other period was during Arab migration with the expansion of Islamic empire on 6th century AC. (source Nadia Al-Zahery et al research).

6-To confirm J haplogroup type, deep SNP tests must be used. For J1, M267 SNP must be positive. Many other SNP are being discovered as research progresses which links smaller groups together (tribes and clans) such as the Big Y test by FTDNA which will draw the YDNA tree of this unique haplogroup.

7-Main cluster of Arabic J1 holder were found around SNP L222.  Two distinctive groups are visible those are have it and those who don't have have it.  Many researchers have made many conclusions on its link to Adnanite or Qahtanite as well Hashemite linking.  Refer to the research forums on the web form more information.
