TL;DR: Evidence is observed of a higher level of diversity and lower level of population structure in western South America compared to eastern South America, a relative lack of differentiation between Mesoamerican and Andean populations, and a partial agreement on a local scale between genetic similarity and the linguistic classification of populations.

TL;DR: An analysis of admixture in thirteen Mestizo populations from seven countries in Latin America based on data for 678 autosomal and 29 X-chromosome microsatellites found extensive variation in Native American and European ancestry among populations and individuals and evidence that admixture across Latin America has often involved predominantly European men and both Native and African women.

TL;DR: This paper evaluated ancestry in over 1,700 individuals from 24 Colombian populations using biparental (autosomal and X-Chromosome), maternal (mtDNA), and paternal (Y-chromosome) markers.

TL;DR: A preliminary entomological survey of the sand fly species composition was performed using Shannon and CDC light traps in the city of Sincelejo, Colombia as discussed by the authors, where a total of 486 sand flies representing six Lutzomyia species were collected.

TL;DR: The findings indicate that genetic factors can explain the association between asthma and African ancestry and suggest that this sample is a useful resource for performing admixture mapping for asthma.
