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.

    Df(2R)cn83c/Df(2R)CA53 embryos are usually wild-type, but sometimes have segmentation defects and denticles in the third thoracic segment that resemble abdominal denticles. Df(2R)CA53/Df(2R)cn83c ; Scm1/+ embryos lack terminal structures and are U-shaped. Denticle belts of the 3rd to 7th abdominal segments are transformed posteriorly.

    NOT in combination with other aberrations

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

    The Df(2R)CA53 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).

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

    1-3% of male flies carrying Df(2R)CA53 have extra sex combs.

    Ocelli small in heterozygotes.
