I want to know the answer to the following question:
Human geneticists argue that genetic variations have been identified that show high or low frequencies among Ashkenazi Jews?
All the background I'm provided with is that "However, a 2013 study of Ashkenazi mitochondrial DNA, from the University of Huddersfield in England, suggests that at least 80 percent of the Ashkenazi maternal lineages derive from the assimilation of mtDNAs indigenous to Europe, probably as a consequence of conversion.". Is that enough to answer the question?
