We have studied the hypervariable D1S80 locus in 185 individuals from five South American
Indian tribes, integrating these results with previous investigations. Three alleles (* 18,* 24
and* 30) were common to all tribes, but their frequencies varied between northern and
southern populations. Brazilian tribes have a high frequency of* 30 (average 35%) while in
Argentinian and Chilean Indian populations this allele is present, on average, in 7% of the
chromosomes only. Allele* 24, the most common in other ethnic groups, was observed in …

Summary
We have studied the hypervariable D1S80 locus in 185 individuals from five South American Indian tribes, integrating these results with previous investigations. Three alleles (*18, *24 and *30) were common to all tribes, but their frequencies varied between northern and southern populations. Brazilian tribes have a high frequency of *30 (average 35%) while in Argentinian and Chilean Indian populations this allele is present, on average, in 7% of the chromosomes only. Allele *24, the most common in other ethnic groups, was observed in 10% and 25% of northern and southern Amerindians respectively. Genetic distance and dendrogram analyses placed the Argentinian and Chilean tribes closer to Brazilian Caucasians, suggesting non-Indian admixture among them.
