Time of origin 25,000-30,000 years BP
Place of origin Southwest Asia
Ancestor IJ
Descendants J1, J2
Defining mutations 12f2.1, M304, P209, S6, S34, S35

In human genetics, Haplogroup J (previously known as HG9 or Eu9/Eu10) is a Y-chromosome DNA haplogroup. It is defined by the 12f2.1 genetic marker, or the equivalent M304 marker. It evolved in the ancient Near East and was then carried into North Africa, Europe, Central Asia, Pakistan and India.

Origins

Haplogroup J is believed to have arisen roughly 30,000 years ago in Southwest Asia (31,700±12,800 years ago according to Semino et al.. 2004). It is most closely related to Haplogroup I, as both Haplogroup I and Haplogroup J have mutations in common deriving from Haplogroup IJ (S2, S22). Haplogroup IJ and haplogroup K derive from Haplogroup IJK (L15/S137, L16/S138), and only at this level of classification does haplogroup IJK join with Haplogroup G and Haplogroup H as immediate descendants of Haplogroup F. The main current subgroups J1 and J2, which now comprise between them almost all of the population of the haplogroup, are both believed to have arisen very early, at least 10,000 years ago.

Haplogroup J is found in greatest concentration in Southwest Asia. Outside of this region, haplogroup J has a presence in North Africa. It also has a moderate presence in Southern Europe (especially in central and southern Italy, Malta, Greece, and Albania), Central Asia, and South Asia, particularly in the form of its subclade J2 (J-M172). Haplogroup J is also found in Horn of Africa, particularly in the form of its subclade J1 (J-M267). Subclades J2a and J2a1b1 are found mostly in Greece, Anatolia, and southern Italy.

Tree

Below are the subclades of Haplogroup J with their defining mutation, according to the ISOGG tree (as of March 2010). Note that the descent-based identifiers may be subject to change, as new SNPs are discovered that augment and further refine the tree.

Subclades

J1

ISOGG states that J1 originated in the Levant region, other parts of the Near East, and North Africa, with a sparse distribution in the southern Mediterranean flank of Europe, and in Ethiopia. But not all studies agree with this conclusion, a recent 2009 study concluded that the haplogroup at a more Northern origin. The origin of J1c3 is likely in the more northerly populations in and then spreads southward into the Arabian Peninsula." The high YSTR variance of J1c3 in Turks and Syrians supports the inference of an origin of J1c3 in nearby eastern Anatolia. Moreover, the network analysis of J1c3 haplotypes shows that some of the populations with low diversity, such as Bedouins from Israel, Qatar, Sudan and UAE, are tightly clustered near high-frequency haplotypes suggesting founder effects with star burst expansion in the Arabian Desert. " [1] Haplogroup J1, defined by the 267 marker is most frequent in the Arabian Peninsula Yemen(76%)[2], Saudi (64%) [3], Qatar (58%)[4], and Dagestan (56%)[5]. J1 is generally frequent amongst Arab Bedouins (62%[6]. It is also very common among others such as those of the southern Levant, i.e. Palestinians (38.4%) [7], in Algeria (35%)[7], Iraq (28.2%)[7], Tunisia (31%)[8], Syria (30%), Egypt (20%)[9], and the Sinai Peninsula. The frequency of Haplogroup J1 collapses suddenly at the borders of Arabic speaking countries with mainly non-Arabic speaking countries, such as Turkey (9%) and Iran (9.5%) [10]. It is also highly frequent among Jews, especially the Kohanim caste (46%) [1] [11] .

J2

Haplogroup J2 is found in the highest concentrations in the Fertile Crescent and is found throughout the Mediterranean (including Southern Europe and North Africa), the Balkan peninsula, the Caucasus, the Iranian plateau and into Central Asia[7] and South Asia. More specifically it is found in Iraq, Syria, Lebanon, Turkey, Azerbaijan, Iran, Israel, Greece, Italy, the Balkans and the eastern coasts of the Iberian Peninsula[12], and most frequently in Lebanese 30% (Wells et al. 2001), Iraqis 29.7% (Sanchez et al. 2005), Syrians 29%, Kurds 28.4%, Iranians 24%[13], Ashkenazi Jews 24%, Palestinian Arabs 16.8% and Sephardic Jews [2]

Consistent with its Middle Eastern extent, J2 also includes the Cohen Modal Haplotype.

J*

Haplogroup J* includes all of J except for J1 and J2. J* is rarely found outside of the island of Socotra, where it is quite frequent at 71.4%[14]. Haplogroup J* also has been found with lower frequency in Oman,[15] Ashkenazi Jews,[16] Pakistan,[17] Saudi Arabia,[18] Greece,[15] the Czech Republic,[15][19] Mariña Lucense,[20] and several Turkic peoples.[5][10][21]
