We defined the Y-chromosome haplotypes on the basis of six polymorphic sites: an Alu-element insertion (YAP), a single-base change (C-->T at DYS199), one trinucleotide repeat (DYS392) and three tetranucleotide repeats (DYS393, DYS390 and DYS19). Among 140 Y chromosomes from Whites, Blacks, Japanese and Amerindians we identified 67 different haplotypes, the majority of them population-specific; only seven haplotypes were shared by three different racial groups, mostly owing to admixture.
