What is the difference between J1 and J2 haplogroup?
What is the difference between J1 and J2 haplogroup?
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.
What does Y-DNA tell you?
A Y chromosome DNA test (Y-DNA test) is a genealogical DNA test which is used to explore a man’s patrilineal or direct father’s-line ancestry. The Y chromosome, like the patrilineal surname, passes down virtually unchanged from father to son.
What is the origin of Y DNA haplogroup J?
Early origins. The origin of Y-DNA Haplogroup J maps to the Middle East around the ‘Fertile Crescent’, an area also known as the ‘Cradle of Civilization’ since this area saw the birth of many technological advancements that helped humans move from nomadic hunter-gatherers to an agriculture-based society living in one place.
What is the J2 haplogroup?
The J2 subclade is highest in Anatolia and prominent in Mesopotamia and the Levant – all areas that served as centers of agricultural revolution. J2 is common among Turkish, Kurdish and Jewish populations and significant frequencies are found in the Caucasus, Iran, and Southcentral Asia. TMRCA estimates for this haplogroup range from 4-15kya.
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.
Where did j2b1 come from?
J2b1’s TMRCA is 5500 ybp according to Yfull, and many common subclades in the Balkans are much younger than that – only about 1000 years old. We now know thanks to Broushaki et al. 2016 that J2b originated in Neolithic Iran, and indeed J2b1 is particularly common today in Iran (2 to 5%) and is also found in Armenia, the Levant, Pakistan and India.
