    Description

    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.

        In tupunspecified, exexunspecified double mutants the scaffold of CNS axons is aberrant, the commissures are often greatly reduced or absent. ISNb projections clump in the proximity of the ISN. Axons within the ISN defasciculate aberrantly and ISNs from adjacent hemisegments can fuse across the parasegment boundary. Longitudinal connectives are abnormally thin and irregular.
