Insertion within for, 994bp downstream of exon 1.
Mutant flies show a normal initial olfactory startle response to a pulse of ethanol vapour, but show enhanced habituation of the olfactory startle response compared to wild-type controls.
for11.247 is rescued by forUAS.T1/Scer\GAL4for-11.247
Expression of forScer\UAS.T1 under the control of Scer\GAL4for-11.247 rescues the enhanced habituation of the olfactory startle response which is seen in for11.247 flies.
Precise excision of the insertion reverts the abnormal habituation phenotype.
