    In combination with other aberrations

    Df(2L)J27/+ heterozygote showed moderate suppression of In(1)wm4 variegation.

    Suppressor of In(1)wm4h position-effect variegation.

    NOT in combination with other aberrations

    The Df(2L)J27 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 this deletion has no effect on the mutant ovarian phenotype of ovoD2.

    Heterozygotes with Cdk1216P, cdc2E1-23 or cdc2B47 are lethal. Lethality can be partially rescued by expression of P{Cdk1A171T}, P{G43E} or P{P131S} at 18oC, levels of rescue drop at higher temperatures.

    Lowering the dose of stg or cdc2 has no effect on the germline phenotype of rux.

    Wing phenotype of l(1)scUAS.cHa is suppressed.

    Lethal over da
