Expression of PGs shared among tissues and the correlation between expression patterns and the Ks. (a) Overlapping expression of PGs - the majority of expressed PGs are found in all five tissues tested. (b) Pairwise comparisons of tissues with PGs - the numbers in black boxes represent the number of PGs expressed in indicated tissues. The numbers in the upper-right half are the number of PGs expressed in both tissues specified in the top row and in the leftmost column. The numbers in the lower-left half are the percent overlap between two tissues. (c) The relationships between the Ks and transformed correlations in expression patterns - the Ks values were determined for all PG pairs. The correlations between expression patterns were calculated for all PG pairs and transformed as described in the Materials and methods. The formulae for the best fit and the correlation coefficient determined by linear regression are shown on the top right corner.
