Affected Genes Inferred by Location (0)
    If no genes are listed here, it may be because the affected region is very large. The JBrowse insert above may show an error for the same reason, and other FlyBase tools such as CytoSearch may also fail for large regions. You can contact FlyBase for more help.
    In these cases, there will be no "Export to Hitlist" button to the left.
    Phenotypic Data
    In combination with other aberrations
    NOT in combination with other aberrations

    Homozygous lethal at the late first larval instar stage (with no escapers). Homozygotes do not show any gross abnormalities, although they show a sluggish response to physical contact compared to heterozygous controls. Homozygous clones are not recovered in the eye. Females containing homozygous germ-line clones lay no eggs. Oocyte development is arrested before the onset of vitellogenesis in these females.
