      Detailed Description
      Statement
      Reference

      233y-a233y-a virgin females show elevated ovulation; 68% of the virgin females show ovulation (compared to 0% of virgin Oregon-R females). The flies show no obvious defects in viability, fertility, morphology or locomotor activity. The courtship index observed when 233y-a233y-a virgin females are mated to wild-type males is lower than that seen when wild-type virgin females are mated to wild-type males, but is higher than that seen when wild-type mated females are mated to wild-type males. 233y-a233y-a mutant virgin females show ovipositor extrusion towards courting wild-type males (this extrusion behaviour is normally observed in mated wild-type females but not in virgin wild-type females).

      Excision of the P{GawB} insertions in the "233y" line (which contains two insertions; P{GawB}233y-a233y-a and P{GawB}233y-b) reverts the mutant phenotype.
