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.
Homozygotes have rough eyes.
ecunspecified has phenotype, non-enhanceable by E(S)1
E(S)1 has little or no effect on the rough eye phenotype in ecunspecified E(S)1 double heterozygotes.
