  1. ¶I.III.V indicates analysis of additive interaction between regions I and III and V.
  2. §I (III.V) indicates analysis of interaction between region I and combined regions III and V.
  3. ns = no statistically significant difference between observed and expected values.
  4. Positive epistatic interactions are in green.
