Paternal lineages in southern Iberia provide time frames for gene flow from mainland Europe and the Mediterranean world
The particular Andalusian R1b-M269 assemblage confirms the shallow topology of the clade. Moreover, the sharing of lineages with the rest of Europe indicates the impact in Iberia of an amount of pre-existing diversity, with the possible exception of R1b-DF27. Lineages such as J2-M172 and G-M201 highlight the importance of maritime travels of early farmers who reached the Iberian Peninsula
MtDNA and Y‐chromosome diversity in Aymaras and Quechuas from Bolivia
Two Bolivian samples belonging to the two main Andean linguistic groups (Aymaras and Quechuas) were studied for mtDNA and Y‐chromosome uniparental markers to evaluate sex‐specific differences and give new insights into the demographic processes of the Andean region. mtDNA‐coding polymorphisms, HVI‐HVII control regions, 17 Y‐STRs, and three SNPs were typed in two well‐defined populations with adequate size samples. The two Bolivian samples showed …
Autosomal and X chromosome Alu insertions in Bolivian Aymaras and Quechuas
Thirty‐two polymorphic Alu insertions (18 autosomal and 14 from the X chromosome) were studied in 192 individuals from two Amerindian populations of the Bolivian Altiplano (Aymara and Quechua speakers: the two main Andean linguistic groups), to provide relevant information about their genetic relationships and demographic processes. The main objective was to determine from genetic data whether the expansion of the Quechua language into Bolivia co…

Paleogenetical study of pre‐Columbian samples from Pampa Grande (Salta, Argentina)
Ancient DNA recovered from 21 individuals excavated from burial sites in the Pampa Grande (PG) region (Salta province) of North‐Western Argentina (NWA) was analyzed using various genetic markers (mitochondrial DNA, autosomal STRs, and Y chromosomal STRs). The results were compared to ancient and modern DNA from various populations in the Andean and North Argentinean regions, with the aim of establishing their relationships with PG. The mitochondr…
Y‐chromosome variation in South Iberia
Population of Pedroches Valley, a hypothetical Berber settlement, located in the northwest portion of Córdoba province (Andalusia, Spain), had been analyzed for its Y-chromosome diversity. Moreover, to contextualize this population, 127 Y-chromosomes from a general Andalusia sample and a North African Berber community (Marrakech, Morocco) were also typed. For all samples, 24 single nucleotide polymorphisms of the non-recombining portion of the Y-…
Population genetic dynamics in the French Guiana region
Three sets of genetic markers (blood group plus protein polymorphisms, mitochondrial DNA, and Y-chromosome) were compared in four French Guiana and one Brazilian Amerindian populations. Spearman's rank correlation coefficient between five gene diversity statistics and historical or present-day population sizes showed significant values, indicating loss of diversity due to population bottlenecks. The three sets of markers furnished distinct admixt…
Genetic Position of Andalusians from Huelva in Relation to Other European and North African Populations
An understanding of population relationships in the Mediterranean region is crucial to the reconstruction of recent human evolution. Andalusia, the most southern region of Spain, has been continuously and densely occupied since ancient times and has a rich history of contacts with many different Mediterranean populations. Thus, to understand the Mediterranean peopling process, investigators should analyze the population relationships between the …
An unexpected wide population variation of the G1733A polymorphism of the androgen receptor gene
The androgen receptor (AR) has been proposed as a candidate gene for several cancers (breast, prostate, uterine endometrium, colon, and esophagus). Ethnicity is considered an associated risk factor for some of these cancers. Several case-control genetic studies have been focused in samples of the main ethnic groups, but little is known about the distribution of risk polymorphisms in current populations with accurate ethnic and/or geographic origi…
Diversité des allotypes des immunoglobulines (systèmes Gm et Km) d’une population berbère de la vallée de Tacheddirt (Haut Atlas, Maroc). Comparaison à d’autres populations africaines et européennes e…
Le polymorphisme des allotypes Gm et Km des immunoglobulines humaines a été analysé dans une population berbère du Haut-Atlas marocain. Il a été comparé à 18 autres populations africaines (dont six berbères et deux touaregs) et deux populations européennes (française et basque). Tous les sujets sont typés pour les allotypes G1m (1, 2, 3, 17), G2m (23), G3m (5, 6, 10, 11, 13, 14, 15, 16, 21, 24, 28) et Km (1). Les résultats montrent une relative h…
Study of GM immunoglobulin allotypic system in Berbers and Arabs from Morocco
The GM immunoglobulin allotype polymorphism was investigated in four Moroccan populations: three Berber groups from Khenifra (Middle Atlas), Amizmiz (High Atlas), and Bouhria (Beni Snassen) and one Arabic-speaking sample from the Doukkala area (Abda, Chaouia, Doukkali, and Tadla districts in south-central Morocco). In order to characterize the genetic relationships between the populations, our results were compared with those obtained for other N…
Characterisation of the digital dermatoglyphic in a berber population of the high Atlas (Marrakesh, Morrocco)
With an aim of characterising the genetic structure of the Berber population, of the Western High Atlas (Marrakesh), and of locating it compared to the other known populations, a preliminary study of the digital dermatoglyphes relating to a sample of 100 individuals (50 men and 50 women) non related taken at random in the population of the commune of Asni (Wilaya de Marrakesh) was carried out. The frequencies of the digital figures obtained in th…
Diversité génétique de l'allèle O dans des populations berbères
We analysed the O allele polymorphism in a sample of 33 Berbers from the Siwa population, all of them of phenotype O and unrelated to one another. The results show an important genetic diversity considering the limited number of individuals under study. The population must have been in contact with other people in spite of the geographical and cultural isolation. Siwa was an important stopping place for caravans in the desert: it was subjected to…
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
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
GM and KM immunoglobulin allotypes in a Spanish Pyrenean population
Four hundred and thirteen unrelated individuals (202 autochthonous and 211 non-autochthonous) of Val d'Aran (Catalan Pyrenees) have been analysed for the GM and KM immunoglobulin genetic system using the inhibition haemagglutination method. This population was defined by eight GM haplotypes (GM*3 23 5*, GM*3 5*, GM*1,17 21,28, GM*1,2,17 21,28, GM*1,17 5*, GM*1,17 5,6,11,24, GM*1,17 10,11,13,15 and GM*1,17 10,11,13,15,16) inferred from the 17 obse…
Gm and Km allotypes in Wayampi, Wayana and Emerillon Indians from French Guiana
We have studied 506 Amerindians from three French Guiana groups: 194 Wayampi, living in Trois-Sauts, and 100 in the Camopi area; 47 Emerillon also living in the Camopi area and 165 Wayana on the Litani and Maroni rivers. All samples were tested for G1m(1,2,3,17), G3m(5,6,10,11,13,14,15,16,21,24,28) and Km(1) by the classical method of hemaglutination inhibition. The phenotype and haplotype distributions are presented and have been subjected to fa…
