Comparing pre-test walking speed of mutant and wild-type CS flies in the first section indicates significant differences (Kruskal-Wallis test: H = 127.9, P = 0.000). Comparing wild-type CS and wbl flies raised at different temperatures indicates significant differences for 18 and 29°C rearing conditions (U-tests: 18°C, Z = 2.68, P < 0.01; 25°C, Z = 1.39, P = N.S.; 29°C, Z = 2.78, P < 0.01). In the final set of experiments, there were significant differences in pre-test walking activity (Kruskal-Wallis test: H = 131.4, P = 0.000). Significance levels compared to CS in each section are shown. See legend of Figure 2 for levels of significance denoted by the asterisks.
