Africa presents the most complex genetic picture of any continent, with a time depth for mitochondrial DNA (mtDNA) lineages >100,000 years. The most recent widespread demographic shift within the continent was most probably the Bantu dispersals, which archaeological and linguistic evidence suggest originated in West Africa 3,000-4,000 years ago, spreading(More)
Recently, there has been much debate about what kinds of genetic markers should be implemented as new core loci that constitute national DNA databases. The choices lie between conventional STRs, ranging in size from 100 to 450 bp; mini-STRs, with amplicon sizes less than 200 bp; and single nucleotide polymorphisms (SNPs). There is general agreement by the(More)
The Great Lakes lie within a region of East Africa with very high human genetic diversity, home of many ethno-linguistic groups usually assumed to be the product of a small number of major dispersals. However, our knowledge of these dispersals relies primarily on the inferences of historical, linguistics and oral traditions, with attempts to match up the(More)
Allele frequencies for the high polymorphic short tandem repeats (STR) loci PentaE, PentaD, D18S51, D21S11, TH01, D3S1358, FGA, D16S539, D7820, D13S317, vWA and D81179 were analysed in an native Amerindian population from Mato Grosso do Sul state named Terena. Deviations from Hardy–Weinberg expectations were evaluated and the results showed no differences(More)
