History and description of Haplogroup J2 (Y-chromosomal DNA) and its subclades. Haplogroup J2 is a major West Asian and Greco-Roman paternal lineage. It is associated with many Bronze & Iron Age ancient civilizations from the Mediterranean to India.

In human genetics, Haplogroup J-M172 or J2[Phylogenetics 1] is a Y-chromosome haplogroup which is a subclade (branch) of haplogroup J-M304. [Phylogenetics 2] Haplogroup J-M172 is common in modern populations in Western Asia, Central Asia, South Asia, Southern Europe, Northwestern Iran and North Africa.

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 …

J2-M172 diversified approx. 28,000 years ago in or near Western Asia. Learn More... Goals : study the pedigree relationships (phylogeny) of J2 lineages ( subclades ).

2016年8月31日 · Haplogroup J2a-M410 distribution in Eurasia and Northern Africa. J2a spreads from Europe to Southern Asia, with presence also on the African Mediterranean coast. The center of distribution and probable origin is in Northern Fertile Crescent between Asia Minor (modern eastern Turkey), Syria, Armenia, Caucasus and Mesopotamia (modern Iraq).

The Y chromosome is passed from father to son remaining mostly unaltered across generations, except for small traceable changes in DNA. By tracking these changes, we constructed a family tree of humankind where all male lineages trace back to a single common ancestor who lived hundreds of thousands of years ago.

2020年12月30日 · Based upon the methodology posted here and using the sample set described here, as of January 2019 it appears that there are six ancestral Y-DNA lines in haplogroup J2 in the Ashkenazi Jewish...

Haplogroup J2 is carried by 6% of Europeans and its frequency drops dramatically as one moves northward away from the Mediterranean. Sephardic Jews have roughly twice as much J2 as J1 and Ashkenazi Jews have a near equal proportion of J1 and J2 haplogroup markers.

It is biased against customers of Y-clusters or regions of which descendants do more BigY/NGS testing (Ashkenazi/Europe, Northwest Europe, Georgia, Armenia, Rhine/Germans, Arabia, Russia, others Europe ...

Haplogroup J2, believed to have originated in the Middle East between 15,000 and 22,000 years ago, is associated with significant Neolithic expansions, particularly linked to cattle and goat domestication.
