Epistatic network among SNPs with significant epistatic effect on metatarsus circumference (MeC). A node represents a SNP. The chromosome in which the SNP is located is shown in the circle. A pair of SNPs connected by an edge had a significant interaction. The color of a node represent the P-value of the interaction (P < 1.0 × 10−12 = red; P < 1.0 × 10−11 = blue; P < 1.0 × 10−10 = green; P < 1.0 × 10−9 = white). The color of the edge indicates the type of epistatic effect (AA = red; AD = purple; DA = blue; DD = green). Genes in the LD blocks were listed
