Mutant adults show a siginifican under-recruitment of photoreceptors in the eye. Misrotation of ommatidia is not seen.
Homozygous ommatidia show a reduction in the number of photoreceptor neurons.
Homozygotes have a rough eye phenotype.
95% homozygotes are viable. Homozygotes exhibit a rough eye phenotype, ommatidia have variable and reduced numbers of rhabdomeres and defects in the retinal basement membrane (cells with rhabdomeres appear below the retina). Hemizygotes exhibit enhanced rough eye phenotype and reduced viability.
