Jewish group of branches: J2b


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 J2b Jewish branches are old narrow lines. A nice analysis was written by Chris Rottensteiner on the diversity and subgroups of L283. He reports also two subgroups (Z8429) that might both descend from an ancester after the start of Judaism. One branch in Jewish India and one in the Ashkenazi countries.
