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

    Chromosome in combination with In(3R)Na shows the presence of 87A puff and the absence of 87C puff after heat shock.

    (Gausz et al., 1980)
    NOT in combination with other aberrations

    The distal half of the salivary gland turns but the proximal half does not in embryos homozygous for Df(3R)kar-Sz12 by stage 14.

    (Jattani et al., 2009)

    Homozygotes show 100% prepupal lethality, with less than 1% of the animals surviving to the third instar larval stage. Mutant larvae have normal behaviour and gross morphology by light microscopy, except for a tendency towards slightly swollen bodies and increased "bursting" when cuticles are initially penetrated for dissection (suggesting increased hemolymph pressure or weaker body walls than normal). The mutant larvae have relatively normal neuromuscular anatomy by light microscopic examination.

    (Karr et al., 2009)

    Df(3R)kar-Sz12/Df(3R)E229 are male sterile.
