Jewish group of branches: R1b-Z2103


The Jewish branches can be grouped according to their Y-DNA characteristics. These characteristics are often related to a period between 10000ybp-4000ybp. Some branches had a founding father effect in that period outside the Middle East which gives information on the location of their ancestor at the time of the founding father. For other branches it is more likely that the ancestors were in the Middle East, where, in most cases, no founding father effect took place and population growth was continuous. An overview of the Jewish groups of branches is present.


The Z2103 is a large haplogroup that originated about 6000 ybp in the North of the Middle East. See e.g. page on Eupedia It is no surprise that many Jewish branches originated in this area.

Most of the branches have a shared ancestor before the start of Judaism. In this group are both Ashkenazi, Sephardic and Mizrahi branches.

A view on the present old branches of R1b-M269 (outside the European branches) can be seen on NGS results of Atanas Kumbarov's Website. On his site you can see the Z2103 branches (Jewish and non-Jewish).
