Fig. 6 — Genomic regions with strong selective signals in the Shaoxing duck (SX) and mallard (MA). a Distribution of F_ST values and log₂(θπ ratio) calculated in 40-kb sliding windows with 20-kb overlap between Shaoxing duck and mallard. The data points in red are genomic regions under selection in the SX duck. b Volcano plot of the differentially expressed genes in the breast muscle and liver of the Shaoxing duck and mallard. Orange splashes indicate significantly upregulated genes. Blue splashes indicate significantly downregulated genes. Grey splashes indicate genes without significant different expression. c F_ST values around the Enpp1 locus. d Tajima’s D values around the Enpp1 locus. The blue and orange lines represent the mallard and Shaoxing duck, respectively. e Allele frequencies of eight SNPs within the Enpp1 gene across 6 groups
