Reduced sugar response in tßh^nM18 mutant flies compared to wild-type flies after 20 h of starvation. (A) Fraction of flies that responded to each concentration of sucrose. (B) Total number of positive responses. Boxplots represent the median (bar), the 75- and 25%-quartiles (box) and data within 1.5 times the interquartile range (whiskers). Data outside 1.5 times the interquartile range are considered as outliers (black dots). Numbers indicate sample size, asterisk denotes significant difference between genotypes (Wilcoxon rank sum test, p = 1.8 × 10⁻¹²).
