Construct: The truncated NΔintra sequence has been replaced by the 'full-length' Nintra coding sequence.
photoreceptor cell R1 | somatic clone
photoreceptor cell R6 | somatic clone
Most NN724.sev mosaic ommatidia have abnormal photoreceptor complements. The R7 cell is insensitive to the presence of NN724.sev. In contrast virtually no normally composed ommatidia in which either R1 or R6 carry NN724.sev are observed.
