“…While several genetic studies have focused on SEA, research on the ethnic groups in Vietnam remains rather limited [17][18][19][20][21][22][23]. Most of these studies either focused solely on the majority group in Vietnam, the Kinh, as representative of the entire country, or are based on a restricted number of SNPs, microsatellites, or only partial sequencing of mtDNA.…”

Vietnam exhibits great cultural and linguistic diversity, yet the genetic history of Vietnamese populations remains poorly understood. Previous studies focused mostly on the majority Kinh group, and thus the genetic diversity of the many other groups has not yet been investigated. Here we analyze complete mtDNA genome sequences and~2.3 Mb sequences of the male-specific portion of the Y chromosome from the Kinh and 16 minority populations, encompassing all five language families present in Vietnam. We find highly variable levels of diversity within and between groups that do not correlate with either geography or language family. In particular, the Mang and Sila have undergone recent, independent bottlenecks, while the majority group, Kinh, exhibits low levels of differentiation with other groups. The two Austronesian-speaking groups, Giarai and Ede, show a potential impact of matrilocality on their patterns of variation. Overall, we find that isolation, coupled with limited contact involving some groups, has been the major factor influencing the genetic structure of Vietnamese populations, and that there is substantial genetic diversity that is not represented by the Kinh.

This is an evidence-based account of a remarkable, but perhaps somewhat underestimated, series of human population movements lasting continuously for around 5000 years. Information has been collected from a wide variety of studies across a range of disciplines and subjected to critical examination. The emergent picture is presented as a Synthetic Total Evidence Model which traces the Austronesian Diaspora from Taiwan via a genes, language and culture trail to Island Southeast Asia. From there two distinct branches are shown to lead one across the Pacific and another through Malaysia and Indonesia then on to Madagascar. Along the way there are many confounding episodes of admixture, language shifts and cultural assimilation. The Pacific branch is shown to contain two distinct groups known as Polynesians and Melanesians with similar, but still individually characteristic, genepools. Despite all these complexities, the evidence does build to a single unified multi-dimensional picture.

“…Herein we provided immunoglobulin, mtDNA and Ychromosome data in two Hmong populations from French Guiana to define the dynamics of the Hmong settlement in the area. The combined use of uni-and biparental genetic markers is a crucial strategy to highlight the demographical patterns of modern human expansion, migration rates, co-evolution of genes with cultural traits, and sex-biased admixture [40][41][42][43][44][45]. Previously, such procedure has furnished interesting insights about the genetic history of the understudied area [8,10].…”

The Hmong Diaspora is one of the widest modern human migrations. Mainly localised in South-East Asia, the United States of America, and metropolitan France, a small community has also settled the Amazonian forest of French Guiana. We have biologically analysed 62 individuals of this unique Guianese population through three complementary genetic markers: mitochondrial DNA (HVS-I/II and coding region SNPs), Y-chromosome (SNPs and STRs), and the Gm allotypic system. All genetic systems showed a high conservation of the Asian gene pool (Asian ancestry: mtDNA=100.0%; NRY=99.1%; Gm=96.6%), without a trace of founder effect. When compared across various Asian populations, the highest correlations were observed with Hmong-Mien groups still living in South-East Asia (Fst<0.05; P-value<0.05). Despite a long history punctuated by exodus, the French Guianese Hmong have maintained their original genetic diversity.
