Fig. 4From: Reconciling multiple genes trees via segmental duplications and lossesThe construction of \(S'\) and T from S and the set of gene trees \(G_1, \ldots , G_k\) (here \(k = 3\)). The black squares indicate the path of \(k - 1\) duplications that must be mapped to \(r(S')\) Back to article page
