The genetic history of the Southern Andes from present-day Mapuche ancestry
(2023)
The southernmost regions of South America harbor some of the earliest evidence of human presence in the Americas. However, connections with the rest of the continent and the contextualization of present-day indigenous ...
Genomic breed composition of pure registered Brazilian Gir
(Springer, 2022-10-01)
Introduction Gir is a Bos indicus breed originally from India, first imported to Brazil in 1850. High-performance Dairy Gir has been systematically selected in Brazil from its arrival. Since the major phenotypic difference ...
Unsupervised detection of ancestry tracks with the GHap r package
(2020-01-01)
The identification of ancestry tracks is a powerful tool to assist the inference of evolutionary events in the genomes of animals and plants. However, algorithms for ancestry track detection typically require labelled ...
Origins, admixture dynamics and homogenization of the African gene pool in the Americas
(Oxford University Press, 2020)
The Transatlantic Slave Trade transported more than 9 million Africans to the Americas between the early 16th and the mid-19th centuries. We performed a genome-wide analysis using 6,267 individuals from 25 populations to ...
Variation in dental morphology and inference of continental ancestry in admixed Latin Americans
(Wiley, 2018)
OBJECTIVES: To investigate the variation in dental nonmetric traits and to evaluate the utility of this variation for inferring genetic ancestry proportions in a sample of admixed Latin Americans. MATERIALS AND METHODS: ...
Origin and dynamics of admixture in Brazilians and its effect on the pattern of deleterious mutations
(National Academy of Sciences, 2015)
While South Americans are underrepresented in human genomic diversity studies, Brazil has been a classical model for population genetics studies on admixture.We present the results of the EPIGEN Brazil Initiative, the most ...
Gallbladder Cancer Risk and Indigenous South American Mapuche Ancestry: Instrumental Variable Analysis Using Ancestry-Informative Markers
(MDPI, 2023)
A strong association between the proportion of indigenous South American Mapuche ancestry and the risk of gallbladder cancer (GBC) has been reported in observational studies. Chileans show the highest incidence of GBC ...
Implications of the admixture process in skin color molecular assessment
(Public Library of Science, 2014)
The understanding of the complex genotype-phenotype architecture of human pigmentation has clear implications for the evolutionary history of humans, as well as for medical and forensic practices. Although dozens of genes ...
