FlyBase curator comment: this entry is used to capture phenotypic information when the particular allele (or allele combination) used by the author could not be determined but the context of the experiment suggests that the phenotype being described is some kind of loss of function.
sequnspecified is rescued by seqUAS.cBa/Scer\GAL4GMR.long
Expression of seqScer\UAS.cBa under the control of Scer\GAL4GMR.long rescues the R7/R8 photoreceptor targeting defects seen when sequnspecified mutant somatic clones are induced in R7 cells.
