Inferred to overlap with: Df(3R)DG2.
Lethal in combination with Df(3R)fruw24. Lethal in combination with Df(3R)frusat15. Lethal in combination with Df(3R)fru4-40.
The Df(3R)Cha7 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(3R)Cha7 results in 1.1% X chromosome nondisjunction and 1.8% fourth chromosome nondisjunction in In(1)FM7/X ; svspa-pol females.
Does not cause unconditional lethality in hybrid females when heterozygous with D.simulans chromosome.
No second site non-complementing phenotype with zipEbr and zipmhc-c6.1.
Shows no maternal enhancement of dpphr4.
Shows no phenotype when heterozygous with 14-3-3ε18A2, and no effect on phl::tor12D.hs.sev when heterozygous with wild type.
Deficient embryos show an uninterpretable mutant midgut phenotype.
Dorsal closure is abnormal in homozygous embryos, and tracheae do not fuse. The midgut epithelium does not completely surround the yolk and midgut constrictions are incomplete.
Df(3R)Cha7 exhibits a bisexual phenotype when in trans with a fru chromosome.
Heterozygosity for this deletion has no effect on the mutant ovarian phenotype of ovoD2.
When heterozygous with fru, males are sterile and exhibit chain behaviour.
