Zero Degeneracy. Schematic diagram representing (a) complete node duplication and (b) partial node duplication in networks. Biological networks know to posses a higher degeneracy at the zero eigenvalue than corresponding random networks. The degeneracy at the zero eigenvalue is signature of presence of node duplication in the network. The detailed explanation is given in Table 3
