The analysis of selection signals during the domestication process of geese involving populations of geese with various characteristics and interpopulation selection signal analyses. A Geese with high reproductive ability versus Sichuan white geese; to identify the selection signals between goose breeds with high reproductive ability and Sichuan white geese. B Geese with low reproductive ability versus Sichuan white geese; to identify the selection signals between goose breeds with low reproductive ability and Sichuan white geese. Sichuan white geese are medium-weight geese. C Geese with heavy body weight versus Sichuan white geese; to identify the selection signals between breeds of high body weight and Sichuan white geese. D Geese with low body weight versus Sichuan white geese; to identify the selection signals between breeds of low body weight and Sichuan white geese. HCFC2 Host cell factor C2, PSD3 Pleckstrin and Sec7 domain containing 3, TGIF1 TGFB-induced factor homeobox 1, TTL Tubulin-tyrosine ligase family, TGFBR2 Transforming growth factor beta receptor 2, MAPKAPK2 Mitogen-activated protein kinase-activated protein kinase 2, RXRG Retinoid X receptor gamma. The breeds with high body weight include Lion head goose. The breeds with low body weight include Huoyan goose, Zi goose, Magang goose, and Taihu goose. The breeds with high-reproductive-ability include Huoyan goose and Zi goose, while the breeds with low-reproductive-ability include Xupu goose, Magang goose, and Lion head goose
