Does not cause unconditional lethality in hybrid females when heterozygous with D.simulans chromosome.
Midgut development of mutant embryos is wild type.
Salivary ducts are absent in homozygous embryos. Malpighian tubule material is not elongated.
Heterozygosity for this deletion has no effect on the mutant ovarian phenotype of ovoD2.
Embryos hemizygous for Df(1)ct-J4 and Df(1)ct4b1 were examined with polarised light microscopy and antibody staining: muscle pattern incomplete due to muscle absences.
Homozygous embryos lack Malpighian tubules and the gut wall is 3--4 fold thicker than wild type at the junction of the posterior and anterior midgut.
