^aFor each cross we set up two contemporaneous crosses using males from one genotype crossed to virgin females of the other genotype and vice-versa. All results are an average of crosses in both directions. Independent lines of RNAi-B52 were used (V38862, V101740, T37519). All flies were in the w¹¹¹⁸ genetic background and the TUG flies co-expressed UAS-Dcr-2.

^bNumber of flies that survived the entire testing period.

^cFlies were entrained for 5 days in LD at the indicted temperature followed by 7 days in complete darkness (DD). Activity data collected during DD was used to calculate free-running periods.

^dPower is a relative measure of rhythm strength.
