I want to know the answer to the following question:
A 2013 study of Ashkenazi mitochondrial DNA was conducted by what university?
All the background I'm provided with is that "Human geneticists have argued that genetic variations have been identified that show high frequencies among Ashkenazi Jews, but not in the general European population, be they for patrilineal markers (Y-chromosome haplotypes) and for matrilineal markers (mitotypes).". Is that enough to answer the question?
