Regions with introgression between Chinese domestic geese and Yili geese individuals. A FST between Yili goose individuals and the Chinese and European domestic goose populations across scoffold NW_013185696.1. The YL goose samples were divided into three groups based on FST values, YL (pop1) includes YL3; YL (pop2) includes YL2, YL5, YL7, and YL8; YL (pop3) includes YL1, YL4, YL6, YL9, and YL10. The blue line represents FST between Yili and European domestic geese, and red line represents FST between Yili and Chinese domestic geese. The gray region indicates the location of the IGF-1 gene. B ML tree constructed using IGF-1 sequences of scaffold region NW_013185696.1 (119,577–179,398 bp). The red frame highlights the branches of Yili goose individuals. C Allele frequencies of three SNPs in the 5′ regulatory region of the IGF-1 gene in goose populations, the SNP names represent their positions
