From: A branching process for homology distribution-based inference of polyploidy, speciation and loss
A gene tree produced by two triplings at generations 1 and 2, followed by a speciation at generation 3, showing the number of paralogous and orthologous 1-, 2- and 3-pairs. The generation of origin of any paralogous pair (same colour dots) or orthologous pair (different colour dots) is that of its most recent common ancestor
