Breakpoint(s) molecularly mapped
Proximal breakpoint 133.5-137 kb distal to the right breakpoint of In(3R)Cbxrv1 (Karch et al., 1985).
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 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.
Homozygous embryos show abnormal gastrulation and cease development early in embryogenesis.
Heterozygosity for this deletion suppresses the mutant ovarian phenotype of ovoD2.
Sterile in heterozygotes and male heterozygotes have rotated genitalia.
is associated with slight reductions in Ubx and abd-A activity.

The Df(3R)C4 chromosome acts as a dominant weak 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), but this is a false positive result (the suppressor is not within the bounds of the deficient region) because the region of the deficiency is covered by one or more nonsuppressing deficiencies.
