Genetic signatures of parental contribution in black and white populations in Brazil Genet. Mol. Biol.
Guerreiro-Junior,Vanderlei; Bisso-Machado,Rafael; Marrero,Andrea; Hünemeier,Tábita; Salzano,Francisco M.; Bortolini,Maria Cátira.
Two hundred and three individuals classified as white were tested for 11 single nucleotide polymorphisms plus two insertion/deletions in their Y-chromosomes. A subset of these individuals (n = 172) was also screened for sequences in the first hypervariable segment of their mitochondrial DNA (mtDNA). In addition, complementary studies were done for 11 of the 13 markers indicated above in 54 of 107 black subjects previously investigated in this southern Brazilian population. The prevalence of Y-chromosome haplogroups among whites was similar to that found in the Azores (Portugal) or Spain, but not to that of other European countries. About half of the European or African mtDNA haplogroups of these individuals were related to their places of origin, but not...
