Foraging behavior and general locomotion offor 189Y and the excision strain E1measured as the mean ± SE (with sample size in parentheses) larval trail lengths in centimeters. The P-element in 189Y was excised with a source of transposase using the Δ2-3system (27). Excisions of the P-element were generated with theEmbedded Image
