    In combination with other aberrations

    Heterozygosity for In(3R)UbxP18 Df(3R)red-P93 results in 1.1% X chromosome nondisjunction and 0.7% fourth chromosome nondisjunction in In(1)FM7/X ; svspa-pol females.

    NOT in combination with other aberrations

    The Df(3R)red-P93 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).

    Mutation changes the level of w expression in ph-plac+3 flies; eye colour is darker.

    Homozygous embryos show abnormal dorsal closure.

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

    Flies heterozygous for Df(3R)red-P93 show no detectable transformation of halteres to wings or third legs to second legs. Flies heterozygous for both Df(3R)red-P93 and ash16 express partial transformation of halteres to wings or third legs to second legs, there is also evidence of a maternal as well as zygotic component to the interaction.

    Df(3R)red/+ progeny of Df(1)C128/+ females show a high frequency of homeotic transformations (Gans et al., 1980).
