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.

    Phenotypic Data
    In combination with other aberrations

    Df(2L)ed-dp/Df(2L)sc19-8 transheterozygotes exhibit delayed ventral furrow invagination, mesoderm spreading defects and a malformed germ band.

    (Mathew et al., 2009)
    NOT in combination with other aberrations

    One copy of Df(2L)sc19-8 moderately suppresses position effect variegation (PEV) at the w locus caused by In(1)wm4.

    One copy of Df(2L)sc19-8 is unable to suppress the telomeric position effect (TPE) in stocks carrying a variegating P{hsp26-pt-T}39C-5 insertion at the telomere of the left arm of chromosome two.

    (Doheny et al., 2008)

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

    (Halsell and Kiehart, 1998)

    Shows no maternal enhancement of dpphr4.

    (Nicholls and Gelbart, 1998)

    Midgut development of mutant embryos is wild type.

    (Bilder and Scott, 1995)

    Homozygous embryos are very abnormal compared to wild-type. The hindgut is short and broad, and the Malpighian tubules are variable in length.

    (Harbecke and Lengyel, 1995)

    Sterile and reduced viability.
