A. Graph of degree distribution representing the fraction of nodes with k degrees (P(k)) versus degree (k) for SET 1 (left) and SET 2 (right). For each microarray platform, the Pearson correlation network across the anatomical meta-profiles was calculated, and both k and P(k) were calculated for different thresholds of Pearson correlation coefficient. Finally, we calculated representative k and P(k) values for three ranges of correlation thresholds as an average of the values at each percent level within that range. Species are represented by colors while correlation thresholds are represented by different line types. Thresholds are indicated in ranges because they represent the average vector of data from five thresholds, at 1 percent increments. B. Distribution of pairwise correlation coefficients of orthologs for human-mouse, human-rat and mouse-rat, for both SET 1 and SET 2. The mouse versus rat comparison exhibits a higher proportion of highly correlated orthologs than either of these species with human.
