TL;DR: A panel of 446 ancestry informative markers (AIMs) optimized to estimate ancestral proportions in individuals and populations throughout Latin America will be useful resources to explore population history of admixture in Latin America and to correct for the potential effects of population stratification in admixed samples in the region.

TL;DR: Investigating and comparing patterns of genetic ancestry in Colombia by studying samples from Native and non-Native populations living in its 5 continental regions found significant differences were observed between Native andNon- Native populations, among non-native populations from different regions and among Native populations fromDifferent ethnic groups.

TL;DR: From the observed genetic backgrounds, it is possible to conclude that a single reference database for the entire country would not be suitable for forensic purposes.

TL;DR: The results of admixture analysis using X-chromosomal markers suggest that the high proportion of African ancestry in the North Pacific coast was primarily male driven, suggesting that the admixture occurred during a period when African people were no longer enslaved.

TL;DR: The data show an increased tendency of the laboratories toward validation of DNA mixture profiles analysis following international recommendations (ISO/IEC 17025:2005), and continuing education in the analysis and interpretation of mixture DNA profiles may also be a priority for the vast majority of forensic laboratories.
