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

    Semilethal and fertile in combination with Df(2L)TW50. Viable and fertile in combination with Df(2L)Sd37.

    (Butler et al., 2001)
    NOT in combination with other aberrations

    Shows a dominant, slightly rough eye phenotype.

    The Df(2L)pr-M1 chromosome may act as a dominant suppressor of telomeric silencing (assayed using the effect of the chromosome on the eye colour phenotype of flies carrying "P{wvar}KR3-2", a stable "brown-red" variant of the P{3'WP-2,wvar}2Lt insertion), but the eye colour phenotype in the presence of Df(2L)pr-M1 overlaps the eye colour phenotype in a wild-type background so it cannot be unequivocally demonstrated that the deficiency chromosome uncovers a suppressor of telomeric silencing.
