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.
schmalspurunspecified has symmetrical commissure phenotype, enhanceable by pntunspecified
schmalspurunspecified is an enhancer of symmetrical commissure phenotype of pntunspecified
surunspecified pntunspecified double mutant embryos show a slightly enhanced fused commissure phenotype compared to the phenotypes of the single mutants. The number of midline glial cells is reduced in the double mutant embryos.
