“…The allele frequency distribution of Taiwanese Han was similar to that of a previous report from Taiwan among 15 of 17 loci, except loci DYS448 and DYS635. The most frequent alleles at loci DYS448 and DYS635 in the previous report were 18 and 21 repeats, respectively, but 19 and 20 repeats, respectively, in our data [5]. The allele frequency distribution among ten (DYS19, DYS385a/b, DYS389I/II, DYS390, DYS391, DYS393, DYS438, and DYS439) of 11 Y-STR loci (except DYS392) of an American Caucasian population was similar to the data of our ENS [30].…”

“…Y haplotype distributions in different population groups and varied types of markers have been widely reported. Extensive large-scale population surveys have been carried out and are still ongoing to increase the forensic databases [3][4][5][6][7]. Population genetic diversity in relation to microsatellite heterogeneity has been investigated to trace human evolution and migration, and phylogenetic trees or multidimensional scaling (MDS) plots based on Y-STR have been described [6][7][8][9][10][11][12][13].…”

The analysis of Y-chromosome short tandem repeat (Y-STR) loci is a powerful tool in forensic casework. The aim of this study was to present the 17 Y-STR loci haplotype distributions of groups of population living in Taiwan and to demonstrate genetic distances between the groups as well as multidimensional scaling plot based on Y-STR genotype data. Five hundred and fifteen DNA samples from unrelated males of seven groups of population, including Taiwanese Han, two groups of indigenous Taiwanese of Taiwan Island, Tao, mainland Chinese, Filipinos, and a group of people with European, Near Eastern, or South Asian ancestry, were analyzed using a commercial kit that co-amplifies 17 Y-STRs. A total of 471 different haplotypes with 440 unique haplotypes were identified. The overall haplotype diversity was 0.9995 +/- 0.0002. High haplotype diversity was observed in six groups of population, except the Tao. These Y-STRs revealed a low discrimination capacity in the Tao population (36.84%), which should be considered in forensic practice. The multidimensional scaling plot of these seven groups of population constructed based on the genetic distances according to 17 Y-STR loci presented a clear patrilineal genetic substructure in the area. Partial Y-STRs profiling reduced the discrimination capacity in most groups of population and distorted the multidimensional scaling plot.

“…The average (arithmetic mean) haplotype frequencies of two southern native populations, Hlai and Cun , were taken for that population, as described (Wen et al 2004a). We assumed the potential admixture started 2,300 years ago, when the Qin army (Central China Han) first entered the Chaoshan area (Ge et al 1997;Wei and Wang 2000;Huang 2002).…”

“…The Chaoshanese belong to the Southern Han (Figs. 1, 2, 3) (Huang 2002;Hu et al 2007;Xu et al 2009). We therefore assume that the same admixture process may have been followed by this population.…”

“…The admixture genetics presented here is consistent with the historical and demographic information available on the Chaoshanese. Regarding migration in Chaoshanese history, southward expansion of the Central China Han to Chaoshan largely involved expedition forces primarily consisting of young or middle-aged male soldiers (Huang 2002;Chen 2006;Hu et al 2007;Xu et al 2009). Such an asymmetrically high male proportion in migrants would have inevitably affected the mate choice, leaving indigenous women as the primary mating targets (Fan 2000).…”

We investigated the Y chromosome of various Chinese populations to determine the patrilineal origin of the Chaoshanese population. Admixture analysis of six specific Y short tandem repeat (STR) loci in 6,292 individual samples taken from 51 populations, including Chaoshanese and Minnanese of our earlier studies, showed that over 85% of the Chaoshanese Y chromosomes were derived from the Central China Han (M (RH): 0.8614; M (BE): 1.1868 ± 0.2054), and a very small portion were from the southern aborigines. These results support a Central China Han origin of the Chaoshanese and additionally reveal that males from the Central China Han were the predominant contributor to the patrilineal genetics of the Chaoshanese. A phylogenetic tree and analysis of molecular variance signified a strong association between Y chromosomes of Chinese populations and their linguistic affiliations, revealing a coevolution of Y chromosome diversity and languages in East Asia.

The Sakishima islands are members of the Ryukyu island chain, stretching from the southwestern tip of the Japanese archipelago to Taiwan in the East China Sea. Archaeological data indicate cultural similarities between inhabitants of prehistoric Sakishima and Neolithic Taiwan. Recent studies based on tooth crown traits show remarkably high inter-island diversity among Ryukyu islanders, suggesting that the Sakishima islanders might have genetic backgrounds distinct from main-island Okinawa people. To investigate the genetic diversity of the Ryukyu islanders, we analyzed mtDNA, Y chromosome, and autosomal short tandem repeat loci in a sample of main-island Okinawa people and Sakishima (Miyako and Ishigaki) islanders whose participated in a previous study of tooth crown morphology. Our phylogenetic analysis of maternal (mtDNA) and paternal (Y chromosome) lineages shows that the Sakishima islanders are more closely related to people from the Japanese archipelago than to Taiwan aborigines. Miyako islanders and the Hokkaido Ainu have the first and second highest frequencies (respectively) of the Y-chromosomal Alu-insertion polymorphism, which is a presumable Jomon marker. Genetic diversity statistics show no evidence of demographic reduction or of extreme isolation in each island's population. Thus, we conclude that 1) Neolithic expansion from Taiwan did not contribute to the gene pool of modern Sakishima islanders, 2) male-lineage of the Ryukyu islanders likely shares a common ancestor with the Hokkaido Ainu who are presumably direct descendants of the Jomon people, and 3) frequent reciprocal gene flow among islands has masked the trace of common ancestry in the Ryukyu island chain.
