Howdy. I study about Pechenegs in the last year almost daily. So I learned a lot about their history that is longer than what Wikipedia reveals.
While studying, I discovered DNA tests, and these tests could clarify their origins in older populations permanently, and also through them I could understand where their traces still exist today.

What do you know about Pecheneg-DNA?

Many thanks to those who will respond. I will appreciate every comment!
