This deletion removes a single ribosomal protein-coding gene (though other genes are also removed).
Inferred to overlap with: Df(2R)BSC399.
Fails to complement Df(2R)PclXM82, Df(2R)Pcl7B, Df(2R)Pcl11B, Df(2R)PC29, Df(2R)P34 and Df(2R)PC66.
Enhancer of In(1)wm4h position-effect variegation.
Flies heterozygous for the deletion do not show a Minute bristle phenotype.
The Df(2R)PC4 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).
Homozygous embryos have abnormal gut morphology.
Does not cause unconditional lethality in hybrid females when heterozygous with D.simulans chromosome.
Weak second site non-complementing phenotype with zipEbr (though not zipmhc-c6.1 : malformed phenotype penetrance 10-24%.
Shows no maternal enhancement of dpphr4.
Shows a dose-sensitive interaction with pbhs.PB.
Uncovers Dsim\jba in D.melanogaster/D.simulans hybrids. Does not uncover Dsim\pm in D.melanogaster/D.simulans hybrids.
Dominantly causes tergite defects in less than 50% of run3 heterozygotes.
Deficient embryos show a variably penetrant mutant midgut phenotype: variable constrictions absent.
Homozygous embryos are very abnormal compared to wild-type and tracheae are not completely connected. Midgut constrictions do not form and Malpighian tubules are poorly differentiated.
Heterozygosity for this deletion enhances the mutant ovarian phenotype of ovoD2.
Semiviable over subDub. Transheterozygotes tend to die during the pupal phase or only eclose halfway. Escapers show rough eyes, etched tergites and blistered or nicked wings. Males and females are sterile.
Fewer larger nuclei.
