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:
- Only a very small percentage of the Iberian people changed to the Jewish religion: less than 1 percent over the period that significant percentage of the Iberian population was Jewish (700-1500 CE).
- Only a small percentage of the present Jewish population has a male line ancestor that changed to the Jewish religion in Iberia. Since more than 50% of the Iberian population is R1b-DF27, we can expect that about 8-10 of the presently known branches changed their religion to the Jewish religion and have male line descendants.
The groups that are reported are:
