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
    NOT in combination with other aberrations

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

    Heterozygosity for Df(2R)stan2 results in 6.6% X chromosome nondisjunction and 10.9% fourth chromosome nondisjunction in In(1)FM7/X ; svspa-pol females.

    Other Comments
     

    The Df(2R)stan2 chromosome acts as a dominant weak 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 this is a false positive result (the suppressor is not within the bounds of the deficient region) because the region of the deficiency is covered by a combination of nonsuppressing deficiencies and deficiencies with suppressors that map to the 2L tip.

    "46F1;47B9" was stated as revision.
