Expression triangles for (A) Seven in absentia homolog genes SIAH1, Siah1a, and Siah2b; and (B) glucose-6-phosphate dehydrogenase genes G6PD, G6pdx, and G6pd2. Values of Ka, Ks, and the correlation coefficient (R) for expression similarity are shown for each pairwise comparison. For each gene, the boxes numbered 1-16 show expression intensities (Affymetrix AD) in 16 tissues as named; boxes A, B, and S show the average intensity (A) across all 16 tissues, the breadth (B; the number of tissues in which the gene is expressed), and the specificity (S; the ratio of maximum expression among all tissue scores to average intensity). Tissue signals (ADs) and average intensity are coded in red, breadth in blue, and specificity in green.
