J2 haplogroup
Explore J haplogroup maps and history here. First you may want to review the concepts of SNP markers and Y-chromosome haplogroups. In terms of age, the first men with the Haplogroup J mutation lived well before anybody in haplogroups to its right in j2 haplogroup tree, j2 haplogroup.
The date of origin for haplogroup J-M was estimated by Batini et al in as between 19, and 24, years before present BP. E approximately 11, ybp. It is likely that J2 men had settled over most of Anatolia, the South Caucasus and the Zagros mountains by the end of the Last Glaciation 12, years ago. Zalloua and Wells and al-Zaheri claimed to have uncovered the earliest known migration of J2, expanded possibly from Anatolia and the Caucasus. Per research by Di Giacomo , J-M haplogroup spread into Southern Europe from either the Levant or Anatolia , likely parallel to the development of agriculture. Semino et al. Di Giacomo , postulating its initial spread with Neolithic farmers from the Near East.
J2 haplogroup
It is believed to have evolved in Western Asia. Haplogroup J-M is believed to have split from the haplogroup I-M roughly 43, years ago in Western Asia, [1] as both lineages are haplogroup IJ subclades. J-M Transcaucasian origin is defined by the M genetic marker, or the equivalent 12f2. The main current subgroups J-M Armenia highlands origin and J-M Zagros mountains origin , which now comprise between them almost all of the haplogroup's descendant lineages, are both believed to have arisen very early, at least 10, years ago. On the other hand, it would seem to be that different episodes of populace movement had impacted southeast Europe, as well as the role of the Balkans as a long-standing corridor to Europe from the Near East is shown by the phylogenetic unification of Hgs I and J by the basal M mutation. Such a geographic hall [ clarification needed ] is prone to have encountered extra consequent gene streams, including the horticultural settlers. Haplogroup J has also been found among two ancient Egyptian mummies excavated at the Abusir el-Meleq archaeological site in Middle Egypt, which date from a period between the late New Kingdom and the Roman era. Haplogroup J-M is found in its greatest concentration in the Arabian peninsula. It also has a moderate occurrence in Southern Europe , especially in central and southern Italy, Malta, Greece and Albania. Some figures above tend to be the larger ones obtained in some studies, while the smaller figures obtained in other studies are omitted. It is found in parts of the Near East , Anatolia and North Africa , with a much sparser distribution in the southern Mediterranean flank of Europe , and in Ethiopia. But not all studies agree on the point of origin. The Levant has been proposed but a study concluded that the haplogroup had a more northern origin, possibly Anatolia.

The global distribution of J2-M sub-haplogroups has been associated with Neolithic demic diffusion. We investigated the Neolithic contribution of demic dispersal from West to Indian paternal lineages, which majorly consists of haplogroups of Late Pleistocene ancestry.

J2 haplogroup
Author: Maciamo Hay. Last update April famous people. Haplogroup J2 is thought to have appeared somewhere in the Middle East towards the end of the last glaciation, between 15, and 22, years ago. This confirms that haplogroup J2 was already found around the Caucasus and the southern Caspian region during the Mesolithic period. The first appearance of J2 during the Neolithic came in the form of a 10, year-old J2b sample from Tepe Abdul Hosein in north-western Iran in what was then the Pre-Pottery Neolithic Broushaki et al. Notwithstanding its strong presence in West Asia today, haplogroup J2 does not seem to have been one of the principal lineages associated with the rise and diffusion of cereal farming from the Fertile Crescent and Anatolia to Europe. It is likely that J2 men had settled over most of Anatolia, the South Caucasus and Iran by the end of the Last Glaciation 12, years ago.

Y-chromosome and mtDNA polymorphisms in Iraq, a crossroad of the early human dispersal and of post-Neolithic migrations. Read Edit View history. Overlooked but not forgotten: India as a center for agricultural domestication. Then across a land gap with a scarcity of J1, the northeast Caucasus shows a strong focus of concentration. It is a pleasure for her to see the accelerating developments in genetic genealogy, and the wide accessibility and application it has for the average human curious about their origins. Our study shows a frequent presence of M68, a rare marker, in various tribes and groups of South India suggests its autochthonous origin. Get started for free with your YDNA journey. Mutation rates at Y chromosome specific microsatellites. Balaresque, P. Received : 17 March The network was constructed using a median joining with maximum parsimony MP algorithm as implemented in the Network 4. Later, a group of citizen scientists with an interest in population genetics and genetic genealogy formed a working group to create an amateur tree aiming at being above all timely. Font-Porterias D.

In Y-chromosome phylogenetics, subclades are the branches of haplogroups. The high local frequencies observed would rather be the result of founder effects , for instance the proliferation of chieftains and kings's lineages through a long tradition of polygamy, a practice that the Russians have tried to suppress since their conquest of the Caucasus in the 19th century. Previously the name Haplogroup S was assigned to K2b1a4. Detailed method of genotyping is given in Text S1. Haplogroup J-M has been shown to have a more northern distribution in the Middle East, although it exists in significant amounts in the southern middle-east regions, a lesser amount of it was found when compared to its brother haplogroup, J-M, which has a high frequency southerly distribution. Human Genetics. Later, a group of citizen scientists with an interest in population genetics and genetic genealogy formed a working group to create an amateur tree aiming at being above all timely. Albarzinji Farhad M. Nature Genetics. Comparison of our data with worldwide data, including Y-STRs of individuals and haplogroup frequencies of individuals, suggested a complex scenario that cannot be explained by a single wave of agricultural expansion from Near East to South Asia. In fact, it seems that many branches of J2a e. Ge, J.
