Fig. 2.
Significant GWAS SNPs and candidate genes for fatty acid composition in Erhualian, Laiwu and DLY pigs. a SNPs that surpass the genome-wide significant threshold are denoted with different colors in each population (red for DLY, green for Erhualian, and blue for Laiwu). Candidate genes at several genome-wide significant loci are indicated. Panels b–g represent the significant regional plots for the SNP that affects the C20:1 content on SSC7 in Laiwu pigs (b), the C20:1 content on SSC7 in Erhualian pigs (c), the C16:1 content on SSC8 in DLY pigs (d), the C14:0 content on SSC12 in Erhualian pigs (e), the C18:0 content on SSC14 in DLY pigs (f) and the C20:0 content on SSC16 in DLY pigs (g), respectively. The top SNP in each plot is indicated in red and the surrounding SNPs in different colors represent different linkage disequilibrium extents (r 2) to the top SNP
