What haplogroup is J2?
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, Northwestern Iran and North Africa.
Where did J2 haplogroup come from?
Origins. Haplogroup J2 is thought to have appeared somewhere in the Middle East towards the end of the last glaciation, between 15,000 and 22,000 years ago. The oldest known J2a samples at present were identified in remains from the Hotu Cave in northern Iran, dating from 9100-8600 BCE (Lazaridis et al.
What is Y full?
YFull is a DNA analysis service that allows customers to analyze raw data files (BAM and CRAM) obtained from next-generation sequencing (NGS). This fascinating journey to its origins is available to anyone who obtained their raw genomic data through Whole Genome Sequencing.
What is a haplogroup subclade?
In genetics, a subclade is a subgroup of a haplogroup. Subclades are often referred to in genealogical DNA tests of human mitochondrial DNA haplogroups and human Y-chromosome DNA haplogroups, where they represent subbranches of major branches on the human family tree.
Who is YFull?
What does J2 M172 stand for?
Naming. The J-M172 (Y-DNA) haplogroup is defined by the M172 SNP DNA marker. It is also known as J2, which is its designation under the older hierarchical naming scheme for Y-DNA haplogroups. To indicate the correspondence, this haplogroup is often designated J2-M172.
What is the difference between M67 and j2a1-m68?
M67 was probably a major Bronze Age lineage expanding from the Caucasus to Greece to the west and the Indus valley to the east. J2a1-M68 is a minor subclade found in Iraq and India. J2a1-M319 has been found chiefly in Greece (esp. in Crete) and Italy, and at low frequencies around Western Europe (perhaps diffused by the Romans).
What is the history of haplogroup J2?
History and description of Haplogroup J2 (Y-chromosomal DNA) and its subclades. Haplogroup J2 is a major West Asian and Greco-Roman paternal lineage. It is associated with many Bronze & Iron Age ancient civilizations from the Mediterranean to India.
Where does j2a1-m47 come from?
J2a1-M47 is found at low frequency (1-5%) in Anatolia, Georgia, Iran, Iraq and Gulf states. J2a1-M67 is the most common subclade in the Caucasus (Vainakhs, Ingushs, Chechens, Georgians, Ossetians, Balkars) and in the Levant (Lebanese, Jews).
