Figure 3From: Refuting phylogenetic relationshipsPrincipal component analysis of the 31 prokaryoticcore genes. This PCA of core genes is based on their degrees of impossibility for the 58 most commonly rejected bipartitions, as reported in the .pharm. In grey, we have drawn the cloud of markers without obviously different phylogenetic signal. The variance explained by each axis is reported along the graph.Back to article page
