Multivariate analyses of the differentially expressed genes in animals with contrasted IL2 production. A two-way hierarchical clustering analysis matrix (A) and Principal Component Analysis gene factor map (B) are represented. In the heatmap, a color-coded gene module is displayed in the colour bars to the left of the dendogram. Each column in the heatmap corresponds to one animal (green for “Low group”; and red for “High group”). Furthermore, green colour represents low adjacency (negative correlation), while red represents high adjacency (positive correlation). In the PCA figure, the quality of representation of a variable on the axis is measured by the squared cosine between the vector issued from the element and its projection on the axis. The genes that contribute most to the separation between the two groups are coloured in red.
