Three strategies to identify 15 genes allowing the discrimination of the porcine breeds. a Venn diagram with the 228 discriminant transcripts identified from one of three methods (Random Forest, sPLS-DA and genes differentially expressed between one breed and all the others); the 228 gene information is available in the Additional file 5. b PCA constructed with the 15 discriminant genes. The 15 discriminant genes are available in Table 4. DU: Duroc; LWF: Large White dam line; LWM: Large White sire line; LR: Landrace; PI: Piétrain
