Fig. 4From: Identification of candidate regulatory genes for intramuscular fatty acid composition in pigs by transcriptome analysisPrincipal component analysis summarizing the separation and similarities among FA profiles for the pigs with extreme FA values. PC1 and PC2 explained 77.40% of the total variance. The visualization of the eigenvectors was implemented to delimit the FA belonging to their respective group (SFA, MUFA, PUFA)Back to article page
