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

    Eyes show mottling with unpigmented spots on a red background.

    (Reuter et al., 1985)

    Weak w position-effect variegation in eye: salt and pepper pattern. Sectors are induced by the presence of strong enhancers. Expressivity of white variegation is ten-fold lower than in In(1)wm4h individuals.
