Fig. 3.

Expression specificity and positive selection across coding and noncoding surveys. Neural tissues and male (reproductive) tissues are highlighted. Circles represent mean rank correlation (r_r,s) between the score for positive selection and specificity to tissues in the Novartis Gene Expression Atlas. Horizontal lines indicate median of means. Green dots on group names indicate two-tailed P values for the Wilcoxon signed-rank test of equal median across coding versus noncoding surveys: one dot, 5 × 10⁻⁴ < P < 0.05; three dots, P < 5 × 10⁻⁶.
