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.
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.
