ABSTRACT
The allelic and haplotype frequencies of 17 Y-STR loci most commonly used in forensic testing were estimated in a sample of 138 unrelated healthy males from Macapá, in the northern Amazon region of Brazil. The average gene diversity was 0.6554 ± 0.3315. 134 haplotypes of the 17 loci were observed, 130 of them unique and four present in two individuals each. The haplotype diversity index was 0.9996 + 0.0009, with the most frequent haplogroups being R1b (52.2 percent), E1b1b (11.6 percent), J2 (10.1 percent) and Q (7.2 percent). Most haplogroups of this population belonged to European male lineages (89.2 percent), followed by Amerindian (7.2 percent) and African (3.6 percent) lineages.
