Distribution of Pearson correlation coefficients. (A) The distribution of correlation coefficients of bidirectional genes average over 46 microarray data sets. (B) The distribution of correlation coefficients of neighboring genes average over 46 microarray data sets. (C) The distribution of correlation coefficients of randomly paired genes average over 46 microarray data sets. Bidirectional gene pairs are more correlated in expression than randomly paired genes (P < 2.2 × 10-16 by the Wilcoxon rank sum test) and neighboring gene pairs (P = 1.17 × 10-11).
