Phylogenetic analysis reveals multiple origins of Chinese gamecocks.

ABSTRACT: Cockfighting is popular worldwide, dating back to 2,800 BC. Primarily, 5 modern Chinese gamecock breeds exist, located in the northeast (Luxi and Henan), west (Turpan), south (Xishuangbanna), and southeast (Zhangzhou) of China. However, whether Chinese gamecocks were derived from a single origin or multiple origins remains controversial. Therefore, this study used next-generation resequencing data to elucidate the origin of Chinese gamecocks by constructing genome-wide and SRY-box transcription factor 5 (SOX5) gene phylogenetic trees. Data from 161 chickens from 27 breeds, including 9 gamecock breeds, were included. Before constructing the SOX5 gene tree, we validated that the pea-comb phenotype mutation in all gamecock breeds was attributed to copy number variation in intron 1 of the SOX5
