Description

In human genetics, Haplogroup J (previously known as HG9 or Eu9/Eu10) is a Y-chromosome haplogroup. It is defined by the 12f2.1 genetic marker, or the equivalent M304 marker.

Haplogroup J is believed to have arisen between 10,000 and 15,000 years ago in the Near East. It is a descendant haplogroup of haplogroup F.

Source

The Cohen Modal Haplotype falls in haplogroup J.

Subdivisions

It is subdivided into two haplogroups, haplogroup J2, defined by the M172 marker, and haplogroup J1, defined by the M267 marker. There are also some haplogroup J Y-chromosomes that belong to neither J1 nor J2, and are said to be in paragroup J*(xJ1,J2). This means that haplogroup J* includes all of J eXcept[sic] for J1 and J2.
