Jewish group of branches: R1b-DF27

Introduction

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.

Characteristics

Five Jewish branches are known in R1b-DF27. From one branch it is known that they arrived in Western Europe in the early years of Ashkenazi Jewry, 1000 ybp.

The Jewish Ashkenazi people have a larger percentage Y-DNA measured than most other groups in the www.ftdna.com website. Their population is in most cases over represented.

On the DF27-project site we find 1500 persons, of which about 1 percent is from the reported Ashkenazi groups. They represent 6 branches. This means that we can draw the following conclusions:

The groups that are reported are:
