“…However, when the ancestry percentages estimated for the population of Macapá are compared with the percentages described in other Brazilian populations, it becomes clear that there is a regional variation regarding the dynamics of crossbreeding in Brazil. Thus, by comparing the results obtained in the population of Macapá with those of populations of different geopolitical regions of Brazil ( Grattapaglia et al , 2001 ; Ferreira da Silva et al , 2002 ; Dellalibera et al , 2004 ; Góes et al , 2004 ; Ribeiro-Rodrigues et al , 2007 ; São-Bento et al , 2008 ; Ocampos et al , 2009 Ribeiro-Rodrigues et al , 2007 ; as well as Godinho NMO, 2008, Tese de Doutorado, Curso de Ciências Biológicas da Universidade de Brasília, DF) and with populations of the Iberian Peninsula ( Ribeiro-Rodrigues EM, 2003 , Dissertação de Mestrado, Curso de Genética Molecular, Universidade Federal do Pará, Belém) ( Table 2 and Figure 1 ), the population of Macapá showed to be closer, in terms of genetic distances, to the population of Belém (F ST = 0.0016), in strict accordance with their geographic location and history of colonization. The Iberian Peninsula (F ST = 0.0036) is clearly the most distinct population, as well as the one of São Paulo (F ST = 0.0029).…”
