FlyBase curator comment: this entry is used to capture phenotypic information when the particular allele (or allele combination) used by the author could not be determined but the context of the experiment suggests that the phenotype being described is some kind of loss of function.
Mutants are more sensitive to the inhibitory effects of 2-aminoethoxydiphenyl borate than wild-type flies, as measured by the effect on the ERG response.
Repeated blue light exposures cause wunspecified trpunspecified flies to respond in a manner similar to white-eyed flies in which the dark-adapted rhodopsin fraction is reduced to 0.5% of the normal level by vitamin A deprivation, even though the amount of visual pigment in wunspecified trpunspecified flies is normal.
