    In combination with other aberrations

    Transmission rate of Dp(1;f)J21A through females to progeny is 28%, Df(1)dm75e19 has no effect on transmission.

    NOT in combination with other aberrations

    Shows dominant enhancement of dominant haltere phenotype caused by Ubx195 and Ubx9.22.

    Does not cause unconditional lethality in hybrid females when heterozygous with D.simulans chromosome.

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

    Shows no maternal enhancement of dpphr4.

    Deficient embryos show a variably penetrant mutant midgut phenotype: midgut smaller.

    Homozygous embryos do not complete head involution, dorsal closure or germband retraction, and have disconnected tracheae. Hindgut length is variable, but always shorter than wild-type, and the Malpighian tubules and the posterior midgut are variably absent or reduced in size.

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

    No significant change in female lethality when in combination with Sxlf1.

    Hemizygous embryos were examined with polarised light microscopy and antibody staining and found to have wild type muscle pattern and contraction.

    Puff formation at 3C11 during intermoult period.

    Cell viable in abdominal cuticle (Ripoll and Garcia-Bellido, 1979, Genetics 91: 443-53). Slight dm phenotype in heterozygotes with Ubl (Mortin and Lefevre, 1981, Chromosoma 82: 237-47). Germ-line clones lethal (Garcia-Bellido and Robbins, 1983, Genetics 103: 235-47).
