Manhattan plots for the white and gray plumage colors in Gang geese. a Whole-genome (scaffold 240–280) Fst-value comparisons between the genomes of white and gray geese. The x-axis of the Manhattan plot shows the genomic position; the y-axis represents the Fst values. All Fst values were calculated in 5 kb windows. b Fst of along scaffold 394 between white and gray geese. The red line represents the highest Fst region. c Proportion of mutations with Fst = 1 in each gene of the candidate genome region
