Origin of R1b in Bashkirs

[khantaz]

About half of Bashkirs have R1b haplogroup, where did they get it from? Is it more prominent among Southern Bashkirs or Northern Bashkirs?

The Bashkirs of southeast Bashkortostan carry R1b-M269* and R1b-L23* at 2.4% and 32.2%, respectively, with a high percentage of R1b-M73 (M269 sister branch) at 23.4%.

Haplogroup R1b-M269 was the dominant lineage of the Yamnaya-Afanasievo group in its R1b-Z2103 sublineage (4th millennium BCE). M269 is inferred to have a shared common ancestor in the 5th millennium BCE.
