The origin patterns, admixture, and selection signatures of the global gamecock populations.

ABSTRACT: The gamecock is a special domestication product of chicken training for cockfighting. With the development of society, factors such as animal protection and social morality have led to a decline in the number of gamecocks. As a crucial category of genetic resources, more measures need to be taken for protection. In this study, we elucidated the origin patterns, admixture, and selection signatures of the global gamecock populations via genome resequencing data. Results suggested multiple origins of global gamecocks. Asian gamecocks have at least five distinct origins, whereas those from Europe and the Americas have a common origin. Admixtures widely occurred from gamecocks to commercial and local chickens. The influences of admixture events are mainly revealed in metabolism and immunity pat
