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

    Does not suppress the zeste phenotype in a z1 w11E4; Tp(1;2)TE35B homologue.

    (Gubb et al., 1990)
    NOT in combination with other aberrations

    Flies heterozygous for the deletion do not show a Minute bristle phenotype.

    (Marygold et al., 2007)

    The Df(2L)b80e3 chromosome does not 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).

    (Mason et al., 2004)

    Suppresses the ommatidial polarity phenotype of dshhs.sev.B. Suppresses the ommatidial polarity phenotype of msnEP549 when driven by Scer\GAL4hs.2sev.

    (Paricio et al., 1999)

    Chromosome has no effect on the physical interaction between tandemly duplicated copies of w+ and z1, despite having breakpoints within the critical region.
