Figure 3. Relationship between ancestral plasticity and evolved expression divergence. Genes exhibiting significant ancestral expression plasticity (i.e. different between high-predation fish reared with and without predator cues) were more likely to also differ in expression between high- and low-predation populations reared without predator cue exposure in both the Aripo (top) and Quare (bottom) lineages. Each circle represents expression differences in a single transcript with statistically significant ancestral plasticity in the high-predation population as well as significant expression differences between high- and low-predation populations. Plastic expression changes were more likely to be in the opposite (white circles) than in the same (grey circles) direction as genetic expression divergence. The number of transcripts in each quadrant is indicated on the graphs. Note that axes differ between plots in order to best visualize variation within each dataset.
