The glycerol hypersensitivity of flies expressing GykdsRNA.Scer\UAS under the control of Scer\GAL4c564 (seen as a reduction in survival on a glycerol only food source) is enhanced if the flies are also heterozygous for g1.
The reduction in the number of dendritic endpoints of dorsal dendritic arborisation neurons which is seen in larvae expressing NakdsRNA.Scer\UAS under the control of Scer\GAL4109(2)80 is not enhanced by g1/+.
g1, we(g) double mutant flies have significantly lower levels of red pigment in their eyes than g1 single mutants. Likewise, Df(1)HA92/g1, we(g)/+ mutants have lower levels of red pigment in the eye than Df(1)HA92/g1 single mutants. Further, g1, Df(1)N-8/+ double mutant flies have less red pigment in their eyes than the g1, we(g) double mutants, while g1, Df(1)N-8/we(g) flies have the least pigment of the mutant combinations described here.
Eye colour: nearly white, with ltd1. Pale eye color due to the absence of pteridines and brown pigment.
