In combination with other aberrations
Df(2L)M36F-S6 is semi-lethal in combination with Df(2L)H20. Surviving males and females are fertile.
Df(2L)RA5/Df(2L)H20 females have reduced fertility.
Df(2L)r10/Df(2L)H20 results in almost complete lethality.
Inferred to overlap with: Df(2L)TW137.
Effect on variegation of y in In(1)y3P and Sb in T(2;3)SbV studied: inactivation of y occurs independently of inactivation of Sb.
Enhancer of In(1)wm4h position-effect variegation.

NOT in combination with other aberrations
Lysates from 4 hour old prepupae heterozygous for Df(2L)H20 show no reduction in caspase activation compared to wild type.
The Df(2L)H20 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(2L)H20 results in 2.8% X chromosome nondisjunction and 0.0% fourth chromosome nondisjunction in In(1)FM7/X ; svspa-pol females.
Heterozygotes show no adult central brain defect.
Df(2L)H20 in combination with a pair of introgressions from D.simulans spanning 30F1-31E7 to 35D7-36A14 Dsim\Int(2L)S and 21A1 to 22D1--23A2 Dsim\Int(2L)D produces sterile male flies. These flies are female sterile.
Heterozygotes are flightless, but show normal muscle patterns, except for a reduced birefringence of the indirect flight muscles compared to those of wild type.
Does not cause unconditional lethality in hybrid females when heterozygous with D.simulans chromosome.
Intermediate second site non-complementing phenotype with zipEbr and zipmhc-c6.1: malformed phenotype penetrance 25-75%.
Shows no maternal enhancement of dpphr4.
Dominantly causes tergite defects in less than 50% of run3 heterozygotes.
Midgut development of mutant embryos is wild type.
Homozygous embryos have a truncated head and the stomodeum is shifted anteriorly.
Heterozygosity for this deletion has no effect on the mutant ovarian phenotype of ovoD2.
Nonmotile germ cells.
