Fig. 2. Percentage of flies emerging during (A) the morning (M) window
(05:0009:00 h) and (B) the evening (E) window (17:0021:00 h) in
selected and control populations during the 5th, 10th, 25th, 40th and 55th
generations. Error bars represent 95% confidence intervals (95%CI) around the
mean across four replicate populations (10 vials per populations) for visual
hypothesis testing.
