Figure 1.

An example reconciliation. primetv-generated illustration of the reconciled tree showing the evolution of the gene family Major Histocompatibility Complex class I in Gorilla, Orangutan, and Tamarin. The species tree is shown in blue and the gene tree in black. Gene tree vertices corresponding to speciations are indicated by circles and are placed inside species tree vertices, while duplications are indicated by squares. Species names are given in italics and gene names in standard format. The numbers below species tree vertices indicate the time intervals corresponding to the incoming edge, the length of which is scaled according to this number.
