I want to know the answer to the following question:
The difference in percentages of the levels of Eu 19 (R1a) chromosomes between Central and Eastern Europeans and the Ashkenazi population would indicate what?
All the background I'm provided with is that "In comparison with data available from other relevant populations in the region, Jews were found to be more closely related to groups in the north of the Fertile Crescent.". Is that enough to answer the question?
