Forensic characteristics and population construction of two major minorities from southwest China revealed by a novel 37 Y-STR loci system

“…The same and similar ethnolinguistic and geographical cluster characteristics observed in our study were also be reported using other genetic markers, such as autosomal STRs and X chromosomal STRs (X-STRs). Take, for example, 15 autosomal STR loci [ 19 ] and 19 X-STRs [ 13 ] based on the same statistical methods in our previous phylogenetic relationship analysis; Guizhou Tujia had an intimate relationship with geographically close populations and the Han populations, whereas far distant from the Tibeto-Burman language-speaking populations. Totally, our findings based on the 37 Y-STRs demonstrate that Guizhou Miao and Guizhou Tujia are genetically similar with geographically close populations and other linguistically close populations, which is in accordance with the autosomal STR and X-STR consequences of geography and language classification.…”

“…In the present study, we used multifarious bioinformatics methods (Rst genetic distance, heatmap, UPGMA, MDS and PCA) to reconstruct the population relationship of Guizhou Tujia and diverse ethnic groups from nine major language families coming from 11 countries (Sinitic: Han, Hui; Tai-Kadai: Bouyei, Dong, Laotian, Thai; Tibeto-Burman: Tibetan, Tujia; Hmong-Mien: Miao, Yao; Turkic: Uighur, Kazakh; Mogolian: Mogolian, Daur; Indo-European: Danish, Indian, Italian; Semito-Hamitic: Bahraini, Arab; Independent: Korean, Japanese). These bioinformatics methods generally employed the population comparisons in the forensic medicine [13][14][15][16][17]. The results showed that there were significant genetic differences between populations belonging to different regions and languages.…”

The Genetic Structure and East-West Population Admixture in Northwest China Inferred From Genome-Wide Array Genotyping

“…Uyghur derived western related ancestry from West Eurasians and South Asians, while the eastern related components were from the East Asians, and the Siberians ( Ma et al, 2014 ; Feng et al, 2017 ; Heizhati et al, 2020 ). Gansu province connecting the Hexi Corridor and the Tibetan-Yi Corridor in northwest China is not only takes part in the west-east Eurasian communication, but also plays an important role in the southwards population expansion which contributed to the formation of Tibeto-Burman speaking population ( Feng et al, 2020 ; Luo et al, 2020 ). Human population genetic researches had been carried out based on low-density genetic markers and limited sample sizes to explore the genetic history of Gansu province ( Yao et al, 2016 ; Yao et al, 2017 ; Wen et al, 2019 ).…”
