In this study we analyzed a sample of the urban population of La Plata, Argentina, using 17 mtDNA haplogroups, the DYS 199 Y-chromosome polymorphism, and 5 autosomal population-associated alleles (PAAs). The contribution of native American maternal lineages to the population of La Plata was estimated as 45.6%, whereas the paternal contribution was much lower (10.6%), clearly indicating directional mating. Regarding autosomal evidence of admixture, the relative European, native American, and West African genetic contributions to the gene pool of La Plata were estimated to be 67.55% (+/-2.7), 25.9% (+/-4.3), and 6.5% (+/-6.4), respectively. When admixture was calculated at the individual level, we found a low correlation between the ancestral contribution estimated with uniparental lineages and autosomal markers. Most of the individuals from La Plata with a native American mtDNA haplogroup or the DYS199*T native American allele show a genetic contribution at the autosomal level that can be traced primarily to Europe. The results of this study emphasize the need to use both uniparentally and biparentally inherited genetic markers to understand the history of admixed populations.
