    The glue granules in the third instar larval g50e mutant salivary glands are similar in size to wild type.

    g50e mutants have roughly one quarter of the amount of red and brown pigment in the eye compared to wild-type flies. g50e mutant male flies show a greater degree of male-male courtship than wild-type flies.

    Eye colour: red pigments are reduced to 24 +/- 2% of wild-type levels in females. Red pigments are reduced to 33 +/- 3% of wild-type levels, brown pigments are reduced to 19 +/- 4% of wild-type levels in males. Malpighian tubule colour: very pale-clear in females, yellow in males (wild-type colour is orange). Testis colour: very pale (wild-type colour is bright yellow).

    Eyes exhibit pigmentation defects and reduced number of pigment granules.

    Eye colour: orange. RK1.

    we(g), g50e double mutant flies have at least a 50% reduction of brown (ommochrome) and red (pteridine) pigments deposited in the eye compared to g50e single mutants. All of the following w alleles when heterozygous with we(g) enhance the eye colour defective phenotype of g50e mutants, leading to a greater reduction of red pigment within the eye: w1118, w1, wa, wbf, wBwx, wco, wch, we, wi, and wt. In contrast, wsat/we(g), g50e mutants have similar levels of red pigment in the eye to single g50e mutants. One copy of the wHSBJ transgene increases the amount of red pigment in both male and female w+, g50e flies. One copy of the w+mC transgene is also sufficient to increase the amount of red pigment in the eyes of both male and female w+, g50e flies. wa3, g50e/Y double mutant flies have similar levels of red pigment in the eye to g50e single mutants. g50e, za double mutants have a reduced amount of red pigment in the eye comparted to g50e single mutants in both male and female flies. Likewise, g50e, z1 double mutant flies show decreased red eye pigment than g50e mutants, although this reduction is greater in female flies than in male flies. w1118, g50e double mutant flies do not show the increased male-male courtship behaviour that single g50e mutants exhibit.
