        Mutant flies show a significant decrease in ommochrome and drosopterin pigment levels compared to wild type.
        (Harris et al., 2011)
        Mutant flies have reduced red pigment in the eye compared to controls.
        (Cheli et al., 2010, Cheli et al., 2010)
        Mutant males have a shortened adult life span compared to controls, with a mean life span of 31.57 days at 25o.
        (Simonsen et al., 2007)
        Eye colour: the drosopterin (red pigment) content of rb1 flies is reduced to 25% of wild type. Eye colour: the drosopterin (red pigment) content of g1 rb1 double mutant flies is reduced to 18% of wild type. Eye colour: the xanthommatin (brown pigment) content of rb1 flies is reduced to 58% of wild type. Eye colour: the xanthommatin (brown pigment) content of g1 rb1 double mutant flies is reduced to 41% of wild type.
        (Kretzschmar et al., 2000)
        Examination of mutant eyes reveal a dramatic decrease in the number of electron dense pigment granules seen surrounding groups of photoreceptor cells. Examination of retinula cells from rb1 mutants reveals normal neuronal anatomy, including normal cytoplasmic synaptic vesicles (SVs). In an assay for larval motility, rb1 mutants performed as well as wild-type larvae. In locomotor assays testing olfactory response to propionic acid, rb1 mutants perform significantly less well than wild-type larvae.

        Reference
        The mispatterning of the eye caused by expression of aosGD16463 under the control of Scer\GAL4GMR.PF is modestly enhanced in a rb1 mutant background.
        (Harris et al., 2011)
        Expression of auxScer\UAS.cHa under the control of Scer\GAL4GMR.PF enhances the loss of red eye pigment that is seen in rb1 flies.
        (Cheli et al., 2010)
        The reduction in red pigment in the eye seen in rb1 blos1ex2 double mutants is more severe than that seen in either single mutant.
        (Cheli et al., 2010)
        rb1 is a complex modifier of the eye phenotype caused by expression of bchsEP2299 under the control of Scer\GAL4GMR.PF.
        (Simonsen et al., 2007)
        The level of pteridine eye pigments in rb1 ; ltd1 double mutant flies are significantly lower than that of the corresponding single mutants.
        (Ma et al., 2004)
        Eye colour: nearly white, with ltd1. Pale eye color due to the absence of pteridines and brown pigment.
