Abstract Y-chromosome haplotypes of 527 non-related males (176 Han, 186 Tibetan, and 165 Yi) in the Tibetan-Yi corridor were analyzed using SureID® PathFinder Plus. In the populations of Han, Tibetans, and Yi, the haplotype diversity was 0.9989, 0.9981, and 0.9993, respectively, and the discrimination capacity was 0.9148, 0.8925, and 0.9576, respectively. Phylogenetic relationships among 12 studied ethnic groups and 7 other ethnic groups in the Tibetan-Yi corridor were investigated. Both multidimensional scaling analysis and phylogenetic reconstructions indicated that Tibetans appeared separated from the Han and Yi ethnic groups in the Tibetan-Yi corridor. Their genetic homogeneity or heterogeneity has not entirely been affected by their geographical distance and linguistic origin. Keywords Y-chromosomal STR . Forensic genetics .

At the eastern margin of the Qinghai-Tibet Plateau, the elevation plunges from over 4000 m above sea level [1] to about 500 m above sea level [2]. This margin is also called the Tibetan-Yi corridor and has been a vital channel for prehistoric ethnic migration since the 6th millennium B.P. [3], generating unique ethnic cultural landscapes. It is also a crucial area for understanding human adaptation to high altitude, as well as the Chinese ethnic migrations. Over the last decade, the Tibetan-Yi corridor has received increasing attention from anthropologists [4], archeologists [5], and ethnologists [6, 7]. Currently, Han, Tibetans, and Yi are the principal residents of this region. Despite this, they are descended from different clans or tribes.

forensic reference database and population history reconstruction, it is essential to clarify the paternal genetic variation among these major ethnic groups. In this study, blood spots were collected on FTA Cards from 527 healthy male individuals of Han (n = 176), Tibetan (n = 186), and Yi (n = 165) ethnicities in the western part of Sichuan Province. All subjects were from 12 different sampling sites in the Tibetan-Yi corridor (Fig. S1). We confirmed that these individuals were unrelated and lived in the region for at least three
