Three topologies for a weak bond Examples of topologies where two δ-syntenies Σ i and Σ j with witness sets S i and S j have a weak bond. Species are ordered by phylogenetic order Sp i Sp i +1. Cases A (g1 is the witness of weak bond) and B (g2 is the witness of weak bond) are considered to be plausible from the evolutionary perspective, while case C (g2 is the witness of weak bond) is difficult to explain. Different colors represent the orthologous and paralogous δ-syntenies emerging from these cases. Vertical links represent synteny while horizontal arrows represent the weak bond.
