Geese are among the most important poultry species in world. The current generally accepted hypothesis is that European domestic geese originated from greylag (Anser anser), and Chinese have two origins, of which swan cygnoides), Yili goose geese. To explain origin demographic history geese, we selected 14 breeds Europe China wild populations whole genome sequencing data were obtained for 74 samples.Population structure analysis phylogenetic trees showed ancestor except Yili, Analysis suggests domestication occurred ~ 3499 years ago 7552 ago. Furthermore, gene flow was observed between their ancestors. introgression had been introgressed by body size may be influenced events some growth-related genes, including IGF-1.Our study provides evidence at genome-wide level advances understanding traits affected events.
