“…The results indicated that our investigated populations share more genetic components with other Tibeto‐Burman‐speaking populations than other adjoining Asians. This is probably explained by the earlier finding of huge population migration from the surrounding lowland onto the Qinghai‐Tibet Plateau through the Tibetan‐Yi corridor since the initial formation of Tibetans in Neolithic time (Yao, Tang, et al, ). In consideration of the factors of contemporary gene flow from surrounding populations, the above‐mentioned results should not be directly interpreted as the origins and history of the Tibetan‐Burmese ethnic corridor populations.…”

Background: Insertion/deletion polymorphisms (InDels), combined with all the desirable features of both short tandem repeat and single nucleotide polymorphism, have been used in archaeological and anthropological research, population genetics and forensic application. Methods: Thirty InDels in 530 individuals residing in the Tibetan-Yi corridor (142 Dujiangyan Tibetans, 164 Muli Tibetans, 187 Xichang Yis, and 37 Yanyuan Mosuos) were genotyped using the Investigator DIPplex. Forensic parameters and allele frequency spectrum were calculated. Genetic relationships between the investigated populations and worldwide and nationwide populations were assessed based on both the allele frequency distribution and genotype data. Results: The combined powers of exclusion were 0.9807 (Dujiangyan Tibetan), 0.9880 (Muli Tibetan), 0.9852 (Xichang Yi) and 0.9892 (Yanyuan Mosuo). The combined powers of discrimination were 0.999999999983 (Dujiangyan Tibetan), 0.999999999942 (Muli Tibetan), 0.999999999982 (Xichang Yi) and 0.999999999962 (Yanyuan Mosuo), respectively. The comprehensive population comparisons among worldwide and nationwide populations uniformly illustrated that the investigated populations have a genetically closer relationship with Tibeto-Burman-speaking populations and geographically adjacent populations. Conclusion: These 30 loci can be regarded as an efficient genetic tool in forensic individual identification and as a supplementary tool in paternity testing in Dujiangyan Tibetan, Muli Tibetan, Xichang Yi, and Yanyuan Mosuo. The genetic proximity between the four populations in the Tibetan-Yi corridor and other populations is strongly correlated with the linguistic origin and geographical distance. K E Y W O R D S

“…Genotyping was performed on the Affymetrix WeGene V1 Arrays covering 596,744 SNPs at the WeGene genotyping centre, Shenzhen. The WeGene V1 arrays were designed to identify all known paternal Y‐chromosome and maternal mtDNA lineages by adding 18963 Y‐chromosome and 4448 mtDNA phylogenetic relevant SNPs to the Infinium Global Screening Array (GSA) (Yao et al, ).

“…It is important to obtain the complete picture of the complex human diversity or landscape of genetic substructure in population genetics, anthropology, and medical genetics. Although whole‐genome sequencing surveys, such as Simons Genome Diversity Panel (Mallick et al, 2016) (SGDP, 300 genomes), 1000 Genomes Project (Genomes Project Consortium et al, 2015) (2504 individuals) and Estonian Biocentre Human Genome Diversity Panel (Pagani et al, 2016) (EGDP, 483 individuals), have been performed, studies of high‐density genetic variations of East Asian have still only targeted a limited number of geographically restricted populations, such as Tibeto‐Burman‐speaking Tibetans (Yao et al, 2017), Turkic‐speaking Uyghurs (Feng et al, 2017), and Mongolic‐speaking Mongolians (Bai et al, 2018). Thus, the population genetic history of central China still remains in its infancy due to limited genetic marker density, small sample size or included population density.…”

Archaeological, genetic, and linguistic evidence has supported the idea that northern China is the original center of modern Sino‐Tibetan‐speaking populations. However, the demographic history of subsequent southward migration and genetic admixture of Han Chinese with surrounding indigenous populations remain uncharacterized, and the language shifts and assimilations accompanied by movement of people, or just an adaptation of cultural ideas among populations in central China is still unclear, especially for Tibeto‐Burman‐speaking Tujia and central Han Chinese populations. To resolve this, we genotyped over 60K genome‐wide markers in 505 unrelated individuals from 63 indigenous populations. Our results showed both studied Han and Tujia were at the intermediate position in the modern East Asian North–South genetic cline and there was a correlation between the genetic composition and the latitude. We observed the strong genetic assimilation between Tujia people and central Han Chinese, which suggested massive population movements and genetic admixture under language borrowing. Tujia and central Han Chinese could be modeled as a two‐way admixture deriving primary ancestry from a northern ancestral population closely related to the ancient DevilsCave and present‐day Tibetans and a southern ancestral population closely related to the present‐day Tai‐Kadai and Austronesian‐speaking groups. The ancestral northern population we suspect to be related to the Neolithic millet farming groups in the Yellow River Basin or central China. We showed that the newly genotyped populations in Hubei Province had a higher proportion of DevilsCave or modern Tungusic/Mongolic‐related northern ancestries, while the Hunan populations harbored a higher proportion of Austronesian/Tai‐Kadai‐related southern ancestries.

The genetic admixture in Tibetan‐Yi Corridor

Abstract: We conclude that there have been huge population migrations from surrounding lowland onto the Tibetan Plateau via the Tibetan-Yi Corridor since the initial formation of Tibetans probably in Neolithic Time, which leads to the current genetic structure of Tibeto-Burman speaking populations.
