I want to know the answer to the following question:
How many geneticists carried out the 2013 trans-genome study?
All the background I'm provided with is that "Thus, analysis of Ashkenazi Jews together with a large sample from the region of the Khazar Khaganate corroborates the earlier results that Ashkenazi Jews derive their ancestry primarily from populations of the Middle East and Europe, that they possess considerable shared ancestry with other Jewish populations, and that there is no indication of a significant genetic contribution either from within or from north of the Caucasus region", the authors concluded.". Is that enough to answer the question?
