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.
Does not cause unconditional lethality in hybrid females when heterozygous with D.simulans chromosome.
Dominantly causes tergite defects in less than 50% of run3 heterozygotes.
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.
Heterozygosity for this deletion has no effect on the mutant ovarian phenotype of ovoD2.
Heterozygotes are flightless, but show normal muscle patterns, except for a reduced birefringence of the indirect flight muscles compared to those of wild type.
Heterozygotes show no adult central brain defect.
Homozygous embryos have a truncated head and the stomodeum is shifted anteriorly.
Intermediate second site non-complementing phenotype with zipEbr and zipmhc-c6.1: malformed phenotype penetrance 25-75%.
Midgut development of mutant embryos is wild type.
Nonmotile germ cells.
Shows no maternal enhancement of dpphr4.
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).
Lysates from 4 hour old prepupae heterozygous for Df(2L)H20 show no reduction in caspase activation compared to wild type.
