2021年10月13日 · Y-chromosome haplogroup J, and its subgroups J1 and J2, are connected with origins in the Arabian Peninsula, Southern Europe and North Africa, and among many men of Ashkenazi Jewish, Arab Bedouin, Uygur and Uzbek origin. Explore J …

Some deep clades of E-V13, G2a, J2b2a and R1b-Z2103 may also be of Slavic origin, but as they have not yet been identified and no regional data is available, these were not been included. They might account for an extra 5 to 10% of Y-chomosomal lineages in Slavic countries.

Of the two main sub-groups, J1 takes up four-fifths of the total and is spread widely on the continent while J2 is more localised around the Mediterranean, Greece, Italy/Sardinia and Spain. There is also limited evidence that the subclade J1 has long been present in Central Asia.

History and description of Haplogroup J1 (Y-chromosomal DNA) and its subclades. Haplogroup J1 is the dominant Arabic and Cohanim paternal lineage. It originated around the Caucasus and expanded during the Neolithic towards East Africa.

To better understand the modes and timing of J1 dispersals, we reconstructed the genealogical relationships among 28... ... fine-grained map of the present day distribution of J1 chromosomes...

Genetic data of Y-chromosome polymorphism and mtDNA control region showed, in Chuetas’ paternal lineages, high prevalence of haplogroups J2-M172 (33%) and J1-M267 (18%).

The allele frequency of the ancient Near East haplogroup T and the genetic variance of haplogroup J2 preserves the memory of Neolithic migrations from the Armenian Highland and Anatolia to Europe...

A higher resolution contour map of haplogroup frequency distribution among Levantine cities (Table S3b and S3c) revealed coast/inland opposing gradients for J1 and J2 .

J is a Middle Eastern haplogroup, divided into the northern J2 and the southern J1. J2 is by far the most common variety in Europe. The map below shows the spread of J2. The darker green color indicates higher numbers of men with J2. "Iran shows some of the highest levels of Haplogroup M172 in the world.

Haplogroup J-M304, also known as J, [Phylogenetics 1] is a human Y-chromosome DNA haplogroup. It is believed to have evolved in Western Asia. [2] . The clade spread from there during the Neolithic, primarily into North Africa, the Horn of Africa, the Socotra Archipelago, the Caucasus, Europe, Anatolia, Central Asia, South Asia, and Southeast Asia.
