Allele Frequency Estimation from Ambiguous Data: Using Resampling Schema in Validating Frequency Estimates and in Selective Neutrality Testing
The development of molecular typing techniques applied to the study of population genetic diversity originates data with increasing precision but at the cost of some ambiguities. As distinct techniques may produce distinct kinds of ambiguities, a crucial issue is to assess the differences between frequency distributions estimated from data produced by alternative techniques for the same sample. To that aim, we developed a resampling scheme that a…

Challenging views on the peopling history of East Asia: The story according to HLA markers
The peopling of East Asia by the first modern humans is strongly debated from a genetic point of view. A north‐south genetic differentiation observed in this geographic area suggests different hypotheses on the origin of Northern East Asian (NEA) and Southern East Asian (SEA) populations. In this study, the highly polymorphic HLA markers were used to investigate East Asian genetic diversity. Our database covers a total of about 127,000 individual…
The Austroasiatic Munda Population from India and Its Enigmatic Origin: A HLA Diversity Study
The Austroasiatic linguistic family disputes its origin between two geographically distant regions of Asia, India, and Southeast Asia, respectively. As genetic studies based on classical and gender-specific genetic markers provided contradictory results to this debate thus far, we investigated the HLA diversity (HLA-A, -B, and -DRB1 loci) of an Austroasiatic Munda population from Northeast India and its relationships with other populations from I…
Hla Genetic Diversity and Linguistic Variation in East Asia
INTRODUCTION Molecular anthropology - the study of human genetic polymorphisms - is now often used to investigate the accuracy of archaeological and/or linguistic hypotheses. One of the classic examples is the use of genetics in an attempt to discriminate between two alternative models for the spread of agriculture in Europe - the demic and the cultural diffusion models - which finally led to a general approval of the former by geneticists, who r…
Human Migrations in Continental East Asia and Taiwan: Genetic, Linguistic, and Archaeological Evidence
Conferences such as this and its predecessor in Périgueux present data on a scale that can often seem overwhelming, particularly to social scientists not versed in the complexities of population genetics and vice versa. The past has been complex in the extreme, and to recover all this complexity event by event would be impossible.We need to propose overarching hypotheses that can account for the comparative data from linguistics, genetics, and ar…
GM haplotype diversity of 82 populations over the world suggests a centrifugal model of human migrations
This study investigates the GM genetic relationships of 82 human populations, among which 10 represent original data, within and among the main broad geographic areas of the world. Different approaches are used: multidimensional scaling analysis and test for isolation by distance, to assess the correlation between genetic variation and spatial distributions; analysis of variance, to investigate the genetic structure at different hierarchical leve…
Genetic Diversity in Tunisia: A Study Based on the GM Polymorphism of Human Immunoglobulins
The GM polymorphism of human immunoglobulins is analyzed in three Berber populations of southern Tunisia and compared to other GM data. Genetic diversity among Tunisian populations is higher than that among Europeans but does not exhibit any significant geographic or linguistic structure. This result suggests a complex pattern of genetic differentiation
A Worldwide Analysis of AG Molecular Diversity Inferred from Serology
Ten population samples from different geographic origins were tested serologically for the AG polymorphism of human beta-lipoproteins. Their haplotype frequencies were used with previously published data to perform a wide analysis of AG genetic differentiations throughout the world. Coancestry coefficients were computed from weighted F(ST)s among populations by using a matrix of molecular distances among AG haplotypes, which is here determined on…
Genetics and history of sub-Saharan Africa
This paper aims to review the contribution of genetic data to the prehistory and history of sub-Saharan African peoples. The authors review briefly paleontologic data, which give limited information about modern Homo sapiens sapiens origins and isolation of present African gene pools. Most linguistic and archaeological theories about African peoples' prehistory are then confronted with the most informative genetic data available. Rhesus, Gm, HLA,…
