In combination with other aberrations

Transmission rate of Dp(1;f)J21A through females to progeny is 28%, Df(1)RK4 weakly decreases transmission.

NOT in combination with other aberrations

Some mutant embryos show minor cuticular abnormalities, with the denticle belt typically being interrupted or missing from abdominal segment A4. A larger number of mutant embryos have more severe phenotypes, such as a complete lack of denticle belts. Mouth hook formation is not affected. Extensive embryonic lethality is seen in mutant animals.

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.

Midgut development of mutant embryos is wild type.

Heterozygosity for this deletion has no effect on the mutant ovarian phenotype of ovoD2.

Hemizygous embryos were examined with polarised light microscopy and antibody staining: muscle pattern abnormal due principally to variably expressed defect in insertion site positioning.
