Global expression coverage. (A) The proportion of probes giving at least 3 out of 4 mismatch calls in either male or female samples for tissue in the MozAtlas and FlyAtlas. (B) Tissue breadth. "House-keeping" genes were identified to have a tau-statistic under 0.15 (n = 909), and narrow expression a tau-statistic above 0.85 (n = 3446). Overall, only a third of genes were detected in all tissues.
