“…4 Microsatellites, also known as short tandem repeats (STRs) have been broadly used for inferring human population history [22][23] and relationships among continental populations 24 as well as between geographically contiguous populations. [25][26][27] In this research work, autosomal STR variation analysis of 10 present-day Khon Mueang villages from the areas of Yuan settlement, as well as 10 other populations, who had an important role in northern Thai history (and, hence, could potentially be parental populations of the Khon Mueang) were performed, to investigate the population affinity of the studied populations and to explore the level of admixture in the Khon Mueang. 7 were also included in this study.…”

Genetic affinity and admixture of northern Thai people along their migration route in northern Thailand: evidence from autosomal STR loci

The Khon Mueang (KM) are the largest group of northern Thai people. Our previous mtDNA studies have suggested an admixture process among the KM with the earlier Mon-Khmer-speaking inhabitants of this region. In this study, we evaluate genetic affinities and admixture among 10 KM populations in northern Thailand lying along the historical Yuan migration route, and 10 neighboring populations belonging to 7 additional ethnic groups: Lawa, Mon (Mon-Khmer-speaking groups), Shan, Yuan, Lue, Khuen and Yong (Tai-speaking groups) by analyzing 15 hypervariable autosomal short tandem repeat loci. The KM exhibited close relationships with neighboring populations, especially the Tai-speaking groups, reflecting an admixed origin of the KM. Admixture proportions were observed in all KM populations, which had a higher contribution from the parental Tai than the Mon-Khmer groups. Different admixture patterns of the KM along the migration route might indicate high heterogeneity among the KM. These patterns were not directly associated with geographical proximity, suggesting other factors, like variation in the timing of admixture with the existing populations may have had an important role. More genetic data from different marker systems solely transmitted through the male or female lineages are needed to complete the description of genetic admixture and population history of the KM.

“…Hence, in order to obtain a robust reconstruction of the evolutionary history of these islanders, we carried out a study on three of the six aboriginal populations (the Great Andamanese, Onge and Nicobarese) employing autosomal microsatellite markers. These markers have been analysed extensively for inferring genetic relationships among continental populations (Deka et al 1999) as well as between geographically contiguous populations (Reddy et al 2001(Reddy et al , 2005Pandu et al 2006;Thangaraj et al 2006a). The present analysis, using autosomal microsatellite markers on the Andaman and Nicobar Islanders, reveals the molecular diversity present among these isolated, vanishing population groups and explicates their genetic relationship with other populations.…”

Our mtDNA and Y chromosome studies lead to the conclusion that the Andamanese ''Negrito'' mtDNA lineages have survived in the Andaman Islands in complete genetic isolation from other South and Southeast Asian populations since the initial settlement of the region by the out-of-Africa migration. In order to obtain a robust reconstruction of the evolutionary history of the Andamanese, we carried out a study on the three aboriginal populations, namely, the Great Andamanese, Onge and Nicobarese, using autosomal microsatellite markers. The range of alleles (7-31.2) observed in the studied population and heterozygosity values (0.392-0.857) indicate that the selected STR markers are highly polymorphic in all the three populations, and genetic variability within the populations is significantly high, with a mean gene diversity of 77%. The Andaman ''Negrito'' populations do not show particular affinities either with the African populations or with the Indian populations, confirming their unique origin. In contrast, Nicobarese show close affinities with the Southeast Asian populations, suggesting their recent entry in the Islands.
