In combination with other aberrations
Df(2L)MN-6 is semi-lethal in combination with Df(2L)TW50. Surviving females have reduced fertility (male adults are not recovered).
Df(2L)MN-casspr shows reduced viability in combination with Df(2L)TW50.
Df(2L)T317/Df(2L)TW50 animals are viable and fertile.
Df(2L)TW50 is semi-lethal in combination with Df(2L)cact-255rv64.
Inferred to overlap with: Df(2L)TW137.
Viable and fertile in combination with Df(2L)pr2b. Viable and fertile in combination with Df(2L)pr37. Semilethal, male fertile and female subfertile in combination with Df(2L)pr11163. Semilethal and fertile in combination with Df(2L)pr-M1. Viable, male fertile and female subfertile in combination with Df(2L)pr49. Viable, male sterile and female subfertile in combination with Df(2L)pr8311. Male sterile in combination with Df(2L)pr1122. Semilethal and male and female sterile in combination with Df(2L)TW1. Semilethal in combination with Df(2L)TW161.
No effect on In(1)wm4h position-effect variegation.
NOT in combination with other aberrations
Intermediate second site non-complementing phenotype with zipEbr and zipmhc-c6.1: malformed phenotype penetrance 25-75%.
Shows no maternal enhancement of dpphr4.
Shows a dose-sensitive interaction with pbhs.PB.
Deficient embryos show an uninterpretable mutant midgut phenotype.
Mutation does not affect the level of w expression in ph-plac+3 flies.
Homozygous embryos are very abnormal compared to wild-type. The Malpighian tubule primordium forms but individual tubules do not bud out.
Heterozygosity for this deletion has no effect on the mutant ovarian phenotype of ovoD2.
Severe morphological defect.
Associated with a dominant very weak Minute phenotype.

The Df(2L)TW50 chromosome acts as a dominant moderate 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), but this is a false positive result (the suppressor is not within the bounds of the deficient region) because the region of the deficiency is covered by one or more nonsuppressing deficiencies.
