Figure 4. Genetic ablation of CheB42a/llz expressing cells does not affect male courtship behavior.

A. Expression of the proapoptotic genes hid and rpr in CheB42a/llz-expressing cells using the UAS-GAL4 system did not affect male courtship latency (time from female introduction until the male shows any courtship related behaviors). Parental lines crossed to the reciprocal wild-type genetic background were used as controls. Although there were significant differences between the two parental controls, neither control line was statistically different from the focal cross (ANOVA). N  =  (Che/llz-GAL4 x yw, 33; Che/llz-GAL4 x UAS-rpr, hid, 52; w¹¹¹⁸ x UAS-rpr, hid, 27). B. Genetic ablation of Che/llz-expressing cells resulted in a mild effect on male courtship index (the proportion of time a male spends courting once courting started). Genotypes and sample sizes as in A. *, P<0.05.
