of the five Brazilian geopolitical regions. The SNPs assigned apart the parental populations from each other and thus can be applied for ancestry estimation in a three hybrid admixed population. Data was used to infer genetic ancestry in Brazilians with an admixture model. Pairwise estimates of F(st) among the five Brazilian geopolitical regions suggested little genetic differentiation only between the South and the remaining regions. Estimates of ancestry results are consistent with the heterogeneous genetic profile of Brazilian population, with a major contribution of European ancestry (0.771) followed by African (0.143) and Amerindian contributions (0.085). The described multiplexed SNP panels can be useful tool for bioanthropological studies but it can be mainly valuable to control for spurious results in genetic association studies in admixed populations." An autosomal DNA study from 2009 found a similar profile "all the Brazilian samples (regions) lie more closely to the European group than to the African populations or to the Mestizos from Mexico." According to another autosomal DNA study from 2008, by the University of Brasília (UnB), European ancestry dominates in the whole of Brazil (in all regions), accounting for 65.90% of heritage of the population, followed by the African contribution (24.80%) and the Native American (9.3%); the European ancestry being the dominant ancestry in all regions including the Northeast of Brazil. A study from 1965, "Methods of Analysis of a Hybrid Population" (Human Biology, vol 37, number 1), led by the geneticists D. F. Roberts e R. W. Hiorns, found out the average the Northeastern Brazilian to be predominantly European in ancestry (65%), with minor but important African and Native American contributions (25% and 9%). ReligionNordeste has the largest percentage of Roman Catholics of any region of the country. Culture Nordeste has a rich culture, with its unique constructions in the old centers of Salvador, Recife and Olinda, dance (frevo and maracatu), music (axé and forró) and unique cuisine. Dishes particular to the region include carne de sol, farofa, acarajé, vatapá, paçoca, canjica, pamonha, quibebe, bolo de fubá cozido, sururu de capote and many others. Salvador was the first Brazilian capital. The festival of São João (Saint John), one of the festas juninas, is especially popular in Nordeste, particularly in Caruaru in the state of Pernambuco and Campina Grande in the state of Paraíba. The festival takes place once a year in June. As Nordeste is mostly arid or semi-arid, the Northeasters give thanks
