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

    Strongly suppresses In(1)wm4 variegation.

    (Tartof et al., 1989)

    Suppresses position effect variegation at the w locus caused by In(1)wm4. Dp(2;2)AM18 when present with Df(2L)E66 does not suppress or enhance position effect variegation at the w locus caused by In(1)wm4.

    (Locke et al., 1988)

    Dp(2;2)AM18/Df(2L)E66 does not enhance variegation of In(1)wm4

    NOT in combination with other aberrations

    Suppresses Minute phenotype of M(2)24F.
