Mutants have pigment cell defects in the retina with a failure of the fenestrated membrane. Mutant eye discs show increased apoptosis compared to controls.
RK1 Rough, partially glazed eyes moderately reduced in size. Tarsal claws are unpigmented and possibly reduced.
Eyes somewhat reduced in size, rough and partially glazed. More extreme than svspa-pol but less so than svspa-p61. Tarsal claws unpigmented and possibly reduced; reminiscent of certain lozenge mutants. Pulvilli and accessory female reproductive structures appear normal. Heterozygote with svspa-pol and svspa-p61 has affected tarsal claws as well as rough eyes. Heterozygote with spa has slightly roughened eyes at 25oC but markedly roughened eyes at 18oC; female somewhat more extreme than male. Viability and fertility good. RK1.
