Objectives
The Tibetan‐Yi Corridor located on the eastern edge of Tibetan Plateau is suggested to be the key region for the origin and diversification of Tibeto‐Burman speaking populations and the main route of the peopling of the Plateau.

Materials and methods
We collected blood samples from 10 Tibetan and 10 Han Chinese individuals from Gansu province and genotyped about 600,000 genome‐wide single nucleotide polymorphisms (SNPs).
Results
Our data revealed that the populations in the Corridor are all admixed on a genetic cline of deriving ancestry from Tibetans on the Plateau and surrounding lowland East Asians.
