Properties of intra-species variation of phenotypic noise. A) Boxplot representation of phenotypic potentials of each strain. Each box represents five values, one per biological replicate. The p-value corresponds to the detection of a strain effect by a Kruskal-Wallis test. B-C) Principal component analysis performed on the 76 noise traits that significantly vary across strains. B) Proportion of variance explained by each component (red) as compared to random expectation (black). C) Coordinates of strains along the first two components. The three morphological features mentioned below the x-axis correspond to the traits best contributing to the first component.
