Phenotypic Data

| In combination with other aberrations | Df(2L)M36F-S6 is semi-lethal in combination with Df(2L)H20. Surviving males and females are fertile. Inferred to overlap with: Df(2L)TW137. Enhancer of In(1)wm4h position-effect variegation. Df(2L)H20/Df(2L)TW119 lethal Df(2L)H20/Df(2L)M36F-S5 lethal Df(2L)H20/Df(2L)TW137 lethal Df(2L)H20/Df(2L)T317 lethal Df(2L)H20/Df(2L)TW201 lethal Df(2L)H20/Df(2L)203 lethal Df(2L)H20/Df(2L)330 lethal Df(2L)H20/Df(2L)VA18 lethal | ||
| 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). 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. | ||
