GWAS and haplotype analysis for carcass oblique length in geese. A Frequency distribution of carcass oblique length in 209 Sichuan white geese. B Manhattan plot of GWAS results for carcass oblique length in Sichuan white geese with SNP markers; the threshold is 5.63 × 10−9. The color scale (green to red) represents the density of SNPs in various regions of the genome. C Phenotypic distribution of various haplotypes of SVEP1, which was identified by GWAS to be associated with the carcass oblique length. C Frequency distribution of carcass oblique length in 209 Sichuan white geese. D SNP distribution of four different haplotypes of SVEP1, including the gene region and 1-kb upstream and 500-bp downstream of the gene. The SNP in red font is located within the intronic region of the gene
