Timing of daily activity and mid-day siesta in inbred and transgenic flies.

aYoung male flies were exposed to five days of 12∶12LD at the indicated temperature. For each genotype, the last three days worth of activity was averaged for each individual fly and then a group average was determined. For the transgenic flies, data from at least three independent lines was used.bn, number of flies used to calculate the values shown and that survived the entire testing period.cValues denote zeitgeber time, whereby ZT0 is defined as lights-on.dMorning offset is defined as the ZT time during the morning activity downswing when 50% of peak morning activity was attained.eEvening onset is defined as the ZT time during the evening activity upswing when 50% of peak evening activity was attained.fSiesta time is defined as the length of time between 50% of morning offset and 50% of evening onset. *, significantly different (p t-test) value for VT1.1 inbred or transgenic compared to VT1.2 counterpart. #, significantly different (p t-test) value for p{VT1.1-SNP3/4} compared to either p{VT1.1-SNP3} or p{VT1.1-SNP4}.
