Genetic mapping information
Comments

This deletion removes a single ribosomal protein-coding gene (though other genes are also removed).

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

    Has no effect on the frequency of X-Y chromosome nondisjunction seen in Df(1)X-1-53B males.

    (McKee et al., 2000)

    Df(2R)knSA3 fails to complement Df(2R)XTE-18.

    (Van Daele, 1998.8.11)

    Df(2R)XTE-18/Df(2R)KL32 viable (MacIntyre, pers.comm. 3rd Aug 1993)

    NOT in combination with other aberrations

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

    (Marygold et al., 2007)

    The Df(2R)XTE-18 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)

    Dominantly causes tergite defects in less than 50% of run3 heterozygotes.

    (Duffy et al., 1996)

    Homozygous embryos are very abnormal compared to wild-type.

    (Harbecke and Lengyel, 1995)

    Heterozygosity for this deletion has no effect on the mutant ovarian phenotype of ovoD2.

    (Pauli et al., 1995)

    Defects in gut formation and epidermal patterning.
