From: Reconciling multiple genes trees via segmental duplications and losses
(1) A species tree S. (2) A gene forest \({\mathcal {G}}\) with two gene trees reconciled under the MPR that we denote \(\mu \). The nodes are labeled by the same name of the species they are mapped to but in lowercase. Black squares indicate duplication nodes. Losses are not shown. (3) The same forest \({\mathcal {G}}\) but with another reconciliation \(\alpha \) for the internal nodes. (4) The forest \({\mathcal {G}}[\alpha , f]\), along with a partition into (possible) segmental duplications
