Fig 1.
The map shows the birthplace of sampled Peruvian urban and native individuals. Gray dots are native communities, black dots are towns or small cities.
Table 1.
Genetic diversity values of STR loci in Native and urban Peruvians.
Fig 2.
a) PCA plot based on STR genotypes of urban and Amazon natives Peruvian, US European and US African populations. Dots represent individuals and the colors are associated with geographic origin. The first principal component accounts for 1. 7% of the total variability, while the second principal component accounts for 1. 3%. b) Contributions of each STR allele to PCA plot. The main allele contributors to the first and second PCs are shown.
Table 2.
Inter population diversity fixation index (Fst) values for each STR locus, calculated both for Native Amazon vs urban Peruvian populations and for Native Amazons, urban Peruvians, US Europeans and US Africans.
Fig 3.
a) DAPC of STR genotype database. DAPC of STR genotype database of urban and Amazon native Peruvian, US European and US African populations. Scatter plot showing the first two principal components. Dots represent individuals. b) Loading plot of DAPC. The main allele contributors to individual DAPC clustering are shown.

Composition of DAPC clusters for STR genotypes.
Vertical bars represent the proportion (%) of each cluster in each population. In the table the absolute and relative (%) frequencies of each cluster for each population are reported.
