An example of corrected fish tree. The tree for the ZNF800 gene family before and after correction, restricted to the species Stickleback (S), Medaka (M), Tetraodon (T) and Zebrafish (Z). (1) The original gene tree G given by Ensembl, using the same notation as in figure 2 for duplications, preservable nodes and required orthologs. Gene region analysis gave us the required orthologs P = {(m₁, s₁), (t₁,d₂)}. (2) The species tree associated with the four species. (3) The gene tree given by our correction algorithm.
