    The Df(2R)en30 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).

    Heterozygosity for Df(2R)en30 results in 0.2% X chromosome nondisjunction and 0.5% fourth chromosome nondisjunction in In(1)FM7/X ; svspa-pol females.

    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.

    Shows a dose-sensitive interaction with pbhs.PB.

    Transheterozygotes with enEnci have reduced adult viability and wings with vein defects in the posterior compartment. en mutants can be ranked by strength regarding their ability to induce a ci phenotype: en1 <= Df(2R)en30 <= en4 <= enEnci <= Df(2R)en-SFX31 <= en59.

    Deficient embryos show an uninterpretable mutant midgut phenotype.

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

    Homozygous lethal. Heterozygotes with lethal en alleles are viable but exhibit wing abnormalities.

    Homozygous lethal.

    Homozygous viable

    Claimed to be a viable allele by Kuner et al. despite claimed deficiency and failure to test homozygote by Eberlein and Russell. (Kuner et al., 1985)
