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 "They hypothesized that the differences among Ashkenazim Jews could reflect low-level gene flow from surrounding European populations and/or genetic drift during isolation.". Is that enough to answer the question?
Answer: yes
