From: Weak gene–gene interaction facilitates the evolution of gene expression plasticity
Differences in the ancestral plasticity magnitude (|PC|) between genes showing persisting and evolved plasticity. Comparisons are made for all ACDE genes (upper panel) and for the subset exhibiting reversing ancestral plasticity (lower panel), derived with either brain or liver samples in either H vs. L1 or H vs. L2 population contrasts. Statistical significance is evaluated by Kruskal–Wallis tests (***, ** and blanks indicate P < 0.001, < 0.01, and > 0.05, respectively)
