Historical records and genetic analyses indicate that Latin Americans trace their ancestry mainly to the intermixing (admixture) of Native Americans, Europeans Sub-Saharan Africans. Using novel haplotype-based methods, here we infer sub-continental in over 6,500 evaluate impact regional variation on physical appearance. We find American components correspond geographically present-day structure groups, sources non-Native ancestry, admixture timings, match documented migratory flows. also...
Numerous studies of human populations in Europe and Asia have revealed a concordance between their extant genetic structure the prevailing regional pattern geography language. For native South Americans, however, such evidence has been lacking so far. Therefore, we examined relationship Y-chromosomal genotype on one hand, male geographic origin linguistic affiliation other, largest study American natives to date terms sampled individuals populations. A total 1,011 individuals, representing...
Previous genetic, anthropological and linguistic studies have shown that Roma (Gypsies) constitute a founder population dispersed throughout Europe whose origins might be traced to the Indian subcontinent. Linguistic evidence point Indo-Aryan ethnic groups from North-western India as ancestral parental of Roma. Recently, strong genetic hint supporting this theory came study private mutation causing primary congenital glaucoma. In present study, complete mitochondrial control sequences...
The origin and prevalence of the prehispanic settlers Canary Islands has attracted great multidisciplinary interest. However, direct ancient DNA genetic studies on indigenous historical 17th–18th century remains, using mitochondrial as a female marker, have only recently been possible. In present work, analysis Y-chromosome polymorphisms in same samples, shed light way European colonization affected male Island pools, from conquest to present-day times. Autochthonous (E-M81) prominent (E-M78...
Objectives: To determine the African, European and Native-American paternal contributions in genetic samples from Department of Bolivar (Colombia) with aims establishing (1) possible population substructures, (2) proportion biological African heritage admixed populations European, Amerindian, descent.Methods: Y-SNPs were typed six communities, including Palenque (renowned for its linguistic cultural heritage).Results: Findings reveal a high diversity Y-haplogroups. With exception Palenque,...
The European Gypsies, commonly referred to as Roma, are represented by a vast number of groups spread across many countries. Although sharing common origin, the Gypsy highly heterogeneous consequence genetic drift and different levels admixture with surrounding populations. With this study we aimed at contributing knowledge Roma history studying 17 Y-STR 34 Y-SNP loci in sample 126 Portuguese Gypsies. Distinct hallmarks their past migration route were detected, namely: an ancestral...
Genetic diversity of present American populations results from very complex demographic events involving different types and degrees admixture. Through the analysis lineage markers such as mtDNA Y chromosome it is possible to recover original Native haplotypes, which remained identical since admixture due absence recombination. However, decrease in effective population sizes consequent genetic drift effects suffered by these during European colonization resulted loss or under-representation...
Abstract With this study, we aimed to determine the different male ancestral components of two Native American communities from Argentina, namely Toba and Colla. The analysis 27 Y‐chromosome SNPs allowed us identify seven haplogroups in both samples. Chromosomes carrying M3 mutation, which typically defines haplogroup Q1a3a, were seen most frequently community (90%). Conversely, Q1a3a was represented 34% Colla Y‐chromosomes, whereas R1b1, main representative western European populations,...
Abstract The establishment of Jewish communities in the territory contemporary Portugal is archaeologically documented since 3rd century CE, but their settlement Trás‐os‐Montes (NE Portugal) has not been proved before 12th century. Decree Expulsion followed by Inquisition, both around beginning 16th century, accounted for a significant exodus, as well crypto‐Jewish communities. Previous Y chromosome studies have shown that different share common origin Near East, although they can be quite...
Abstract Objectives We examined internal lineages and haplotype diversity in Portuguese samples belonging to J‐M304 improve the spatial temporal understanding of introduction this haplogroup Iberia, using available knowledge about phylogeography its main branches, J1‐M267 J2‐M172. Methods A total 110 males descent were analyzed for 17 Y‐chromosome bi‐allelic markers seven short tandem repeats (Y‐STR) loci. Results Among individuals ( n = 36), five different sub‐haplogroups identified, with...
