The Local South American Chicken Populations Are a Melting-Pot of Genomic Diversity.

ABSTRACT: Chicken have a considerable impact in South American rural household economy as a source of animal protein (eggs and meat) and a major role in cultural traditions (e.g., cockfighting, religious ceremonies, folklore). A large number of phenotypes and its heterogeneity are due to the multitude of environments (from arid to tropical rain forest and high altitude) and agricultural systems (highly industrialized to subsistence agriculture). This heterogeneity also represents the successive introduction of domestic chicken into this continent, which some consider predating Columbus' arrival to South America. In this study, we have used next-generation restriction site-associated DNA sequencing to scan for genome-wide variation across 145 South American chickens representing local populations fro
