Table 3 Results of randomizations controlling for breadth of expression. The "Aug" (Augmented) data set is that containing the two ligand -receptor sets nominated by Cooper [20]. Bin size indicates the span of breadths of expression considered to be the same in the randomizations. Bin size one implies that only genes of the same breadth were switched with each other. Distances are measured in Mb. P-values are estimated by comparison of observed data with expectations obtained from randomised genomes.
