The ancestry of Brazilian mtDNA lineages.
We have analyzed 247 Brazilian mtDNAs for hypervariable segment (HVS)-I and selected restriction fragment-length-polymorphism sites, to assess their ancestry in different continents. The total sample showed nearly equal amounts of Native American, African, and European matrilineal genetic contribution but with regional differences within Brazil. The mtDNA pool of present-day Brazilians clearly ...
متن کاملSalt and Brazilian ancestry.
Sao Paulo Med J/Rev Paul Med 2001; 119(4):130. Salt and humanity are very old companions. The agricultural revolution started ten thousand years ago, and salt was responsible for where human populations settled because of its food conservation properties. Populations like the Yanomani that do not use salt for preparing food do not like it when salt is added in, as was the case with the Yanomani...
متن کاملThe phylogeography of Brazilian Y-chromosome lineages.
We examined DNA polymorphisms in the nonrecombining portion of the Y-chromosome to investigate the contribution of distinct patrilineages to the present-day white Brazilian population. Twelve unique-event polymorphisms were typed in 200 unrelated males from four geographical regions of Brazil and in 93 Portuguese males. In our Brazilian sample, the vast majority of Y-chromosomes proved to be of...
متن کاملTracing European founder lineages in the Near Eastern mtDNA pool.
Founder analysis is a method for analysis of nonrecombining DNA sequence data, with the aim of identification and dating of migrations into new territory. The method picks out founder sequence types in potential source populations and dates lineage clusters deriving from them in the settlement zone of interest. Here, using mtDNA, we apply the approach to the colonization of Europe, to estimate ...
متن کاملA predominant European ancestry of paternal lineages from Canary Islanders.
We genotyped 24 biallelic sites and 5 microsatellites from the non-recombining portion of the Y chromosome in 652 males from the Canary Islands. The results indicate that, contrary to mtDNA data, paternal lineages of the current population are overwhelmingly (>90%) of European origin, arguing for a highly asymmetric pattern of mating after European occupation. However, the presence of lineages ...
