Figure 2

Effect of sex on total sleep and variance due to sex. Sex affects total sleep and variance of total sleep in a strain dependent manner. Upper Panels: The amount of total sleep for daytime and nighttime is shown for wCS10 and w1118ex strains. Average total sleep in minutes plus standard deviation is shown. Lower Panels: The amount of variance for daytime and nighttime is shown for wCS10 and w1118ex strains. Females = gray bar. Males = white bar. wCS10 females n = 55, wCS10 males n = 48. w1118ex females n = 51, w1118ex males = 50. Asterisks indicate significant differences between male and female flies; *P < 0.05 ***P < 0.001.
