I want to know the answer to the following question:
What is the frequency of Haplogroup R1a in the Sorbs?
All the background I'm provided with is that "The frequency of Haplogroup R1a ranges from 63.39% in the Sorbs, through 56.4% in Poland, 54% in Ukraine, 52% in Russia, Belarus, to 15.2% in Republic of Macedonia, 14.7% in Bulgaria and 12.1% in Herzegovina.". Is that enough to answer the question?
Answer: yes
