Conservation of overlapping genes and OGCs within Metazoa. A. Schematic representation of the procedure for detecting the conservation of overlapping genes (red spots) and OGCs (red pairs) between two species. The same pipeline was applied to each pair of species considered in the analysis. B. Pairwise conservation of overlapping genes within Metazoans. In the first column, the numbers in brackets represent the total number of overlapping genes for that species. C. Pairwise conservation of OGCs within Metazoa.
