Where did haplogroup J originate?
Western Asia
Haplogroup J-M304, also known as J, is a human Y-chromosome DNA haplogroup. It is believed to have evolved in Western Asia. The clade spread from there during the Neolithic, primarily into North Africa, the Horn of Africa, Socotra, the Caucasus, Europe, West Asia, Central Asia, South Asia, and Southeast Asia.
Who has haplogroup J?
In the Arabian peninsula, mtDNA haplogroup J is found among Saudis (10.5–18.8\% J1b) and Yemenis (0–20\% J1b). The J1b subclade also occurs in the Near East among Iraqis (7.1\%) and Palestinians (4\%). In Africa, haplogroup J is concentrated in the northeast.
Where is Haplogroup J-M172 found?
Haplogroup J2 is found with low frequencies in North Africa. J-M172 is found at moderate frequencies among Central Asian people such as Uyghurs, Uzbeks, Turkmens, Tajiks, Kazakhs, and Yaghnobis.
Does M172 have a common origin in India?
( Sengupta 2006) Subclades of M172 such as M67 and M92 were not found in either Indian or Pakistani samples which also might hint at a partial common origin. ( Sengupta 2006)
Where did the Middle East Y-DNA haplogroup J migrate?
Middle East populations belonging to Y-DNA Haplogroup J migrated during or after the Neolithic era to Mediterranean regions and back to Africa; although this did not reach sub-Saharan regions . This spread contributes significantly to populations in European and African countries around the Mediterranean Sea.
What does J-M172 stand for?
In human genetics, Haplogroup J-M172 or J2 is a Y-chromosome haplogroup which is a subclade (branch) of haplogroup J-M304. Haplogroup J-M172 is common in modern populations in Western Asia, Central Asia, South Asia, Europe and North Africa. It is thought that J-M172 may have originated between the Caucasus Mountains, Mesopotamia and the Levant.
