Principle Component Analysis (PCA) depicting the grandparental bacteria treatment effect on gene expression of one-week-old F2-juveniles. PCA to visualize gene categories revealing a significant different gene expression profiles per grandparental control (F0-control), grand-paternal (F0-paternal), grand-maternal (F0-maternal) and grand-biparental (F0-biparental) bacteria treatment groups (Panels a-f) on relative gene expression data (−∆Ct-values) using an Euclidean distance matrix (N = 192). Panel a all immune genes (29 genes-total), Panel b genes of the innate immune system (13 genes), Panel c genes of the innate & adaptive immune system (5 genes); Panel d complement component genes (3 genes); Panel e epigenetic regulation genes (15 genes-total) and Panel f histone acetylation genes (2 genes). The variance in percentage (%) explained by the respective principle coordinates (PCs) is indicated below (for PC1) and besides (for PC2) the corresponding axis. The size (cm) of the grid is indicated by `d´ for dimension in the upper right corner
