The society of genes: networks of functional links between genes from comparative genomics

Table 1 Overlap of nodes and edges between the four types of network

(a)	Nodes	Chromo	Fusion	Phylo	Combined
	Chromo		41 (6)	31 (3)	100 (0)
	Fusion	72 (6)		30 (3)	100 (0)
	Phylo	75 (10)	41 (6)		100 (0)
	Combined	80 (6)	46 (6)	34 (4)
(b)	Edges	Chromo	Fusion	Phylo	Combined
	Chromo		14 (2)	11 (1)	100 (0)
	Fusion	20 (4)		7 (2)	100 (0)
	Phylo	14 (7)	6 (2)		100 (0)
	Combined	43 (10)	30 (7)	38 (11)

Element in row i column j is the percentage of average nodes (a) or average edges (b) in network of type i that are also found in network of type j, with the standard deviation in parentheses. For example, 75% of the nodes found by phylogenetic profiling are contained in the chromo networks. This should, however, be contrasted with the finding that only 14% of the functional links in the phylo networks are in chromo networks.
