Figure 1

Definition of gene families based on gene tree pruning. Figure A represents a species tree with two extant species S a and S b , and their last common ancestor LCA(S a ,S b ). Figure B represents a gene tree within the species tree. This gene tree is represented in simple 3D schema for better visualisation. In a gene tree, squares represent duplication events and circles represent speciation events. Figure C shows how the original gene tree of figure B is pruned in order to define families that correspond to a unique gene of LCA(S a ,S b ).
