Figure 9


Fig. 9. Representative locomotor activity plots of individual (A) early, (B) control, and (C) late flies under constant darkness (DD). The vertical dark bars denote activity and their absence indicate rest. Activity for 10 consecutive cycles is plotted along the ordinate and time of the day in hours along the abscissa. (D) Mean circadian period ({tau}) (h) of the locomotor activity rhythm of the selected and control populations under constant darkness (DD). Error bars represent 95% confidence interval (95%CI) around the mean for visual hypothesis testing. A total of (N=32) early, (N=27) control and (N=37) late flies were used for the estimation of {tau}. (E) Frequency distribution of {tau} of the locomotor activity rhythm of the early, control and late populations. Time (h) is plotted along the x-axis and percentage frequency along the y-axis.
