    The Df(3R)e-N19 chromosome does not 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).

    Macrophages fail to migrate along the ventral cord in homozygous embryos, with much of the ventral abdomen remaining free of macrophages at stage 13-15.

    Homozygous embryos have abnormal gut morphology.

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

    Shows no maternal enhancement of dpphr4.

    Wild type nonanol phenotype; repulsion.

    Deficient embryos show an uninterpretable mutant midgut phenotype.

    Homozygous embryos show incomplete tracheal formation. Midgut primordia do not fuse and Malpighian tubules are variable in length.

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