Phenotypic Data
In combination with other aberrations
NOT in combination with other aberrations	Heterozygosity for this deletion has no effect on the mutant ovarian phenotype of ovo^D2. (Pauli et al., 1995) Heterozygotes with cdc2^216P, cdc2^E1-23 or cdc2^B47 are lethal. Lethality can be partially rescued by expression of P{Dmcdc2^A171T}, P{G43E} or P{P131S} at 18^oC, levels of rescue drop at higher temperatures. (Sigrist et al., 1995) Lethal over da Lowering the dose of stg or cdc2 has no effect on the germline phenotype of rux. (Gonczy et al., 1994) 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{w^var}KR3-2", a stable "brown-red" variant of the P{3\'WP-2,w^var}2Lt insertion). (Mason et al., 2004) Wing phenotype of l(1)sc^Scer\UAS.cHa is suppressed. (Hinz et al., 1994)
