STRIDE analysis applied the set of Eukaryotic gene trees. (A) Numbers of identified gene duplication events are marked on the branches they are observed on and arrows indicate which block of the bipartition the duplicate genes occur in. None of the gene duplication events contradict each other. The maximum parsimony roots have red branches, the branches from which the root is excluded are black. (B) The probabilities for the location of the root calculated by STRIDE. Major groups of species are marked.
