Fig. 4From: Isometric gene tree reconciliation revisitedA counter-example for the original definition of isometric reconciliation. Trees \(G_I\) and \(S_I\) are the input trees, G is the rooted version of \(G_I\) and S is \(S_I\) with duplication nodes added. This reconciliation satisfies Definition 7, but it does not correspond to any evolutionary historyBack to article page
