Figure 3. Synergy and redundancy of gene pairs with respect to Ca²⁺ .

• A
  SRI(G_i,G_j¦C) sorted by average SRI.
• B
  Histogram of SRI showing that most gene pairs are highly redundant with an average score of −0.43 bits.
• C
  The mean rank of all synergistic pairs compared to the mutual information between that gene and Ca²⁺ signals, (spearman r = 0.5, P < 2e‐6), indicating that genes with more information about Ca²⁺ are also more redundant.
