I want to know the answer to the following question:
DNA samples from 1228 Russians show that the Y chromosomes analyzed, all except 20 (1.6%) fall into seven major haplogroups all characteristic to what populations?
All the background I'm provided with is that "DNA samples from 1228 Russians show that the Y chromosomes analyzed, all except 20 (1.6%) fall into seven major haplogroups all characteristic to West Eurasian populations.". Is that enough to answer the question?
Answer: yes
