Y-Chromosome Haplogroup J
Haplogroup J is common in West Asia, particularly in Southwestern Arabian Peninsula. It is also reasonably common in North Africa, and is present at a lower frequency in Southern Europe (particularly Italy, Malta, Greece and Albania), Central Asia and South Asia. It is likely to have arisen around 30,000 years ago in Southwest Asia.
