Factor maps to demonstrate the contribution of variance retained by each principal component for immune genes (29 genes-total) and epigenetic regulation genes (15 genes-total) of one-week-old F2-juveniles. The response variables (genes) are symbolized by arrows whereby the length of the arrow is directional proportional with the contribution of variance of each gene to the total variability. The colour gradient in the left corner highlights the most important genes in explaining the variation (contribution %) retained by the principle components calculated according to [97]
