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.

    NOT in combination with other aberrations

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

    Heterozygosity for Df(2R)vg135 results in 2.7% X chromosome nondisjunction and 1.9% fourth chromosome nondisjunction in In(1)FM7/X ; svspa-pol females.

    Heterozygous adults show fusion of the β lobes in the central brain with intermediate penetrance.

    No second site non-complementing phenotype with zipEbr and zipmhc-c6.1.

    Shows no maternal enhancement of dpphr4.

    Enhances the phenotype of dominant ovo alleles.

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

    Homozygous lethal. Heterozygotes with rdgE1 exhibit absence of a deep pseudopupil after 7 days in constant light.

    Deficient embryos show a variably penetrant mutant midgut phenotype: incomplete constriction formation.

    Homozygous embryos show abnormal head epithelium differentiation.

    Heterozygosity for this deletion enhances the mutant ovarian phenotype of ovoD2.

    Homozygous lethal.

    Does not exhibit dominant flightlessness.

    homozygous lethal

    Other Comments
     

    The Df(2R)vg135 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)Prl 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. In addition, the deficiency chromosome fails to complement lethal mutations of l(2)gl.
