|Nature of the Aberration|
|Class of aberration (relative to progenitor)|
|Formalized genetic data||l(1)ESHS31 << bk1 << l(1)47 << dec-1 << bk2 << l(1)ESHS35|
|Genetic mapping information|
Proximal breakpoint lies between coordinates 3.6 and 4.0 on the molecular map of dec-1.

|In combination with other aberrations|
Df(1)ct4b1/Dp(1;3)sn13a1 viable (Lefevre and Johnson, 1973, Genetics 74:633-45).
|NOT in combination with other aberrations|
Does not cause unconditional lethality in hybrid females when heterozygous with D.simulans chromosome.
Weak second site non-complementing phenotype with zipEbr and zipmhc-c6.1: malformed phenotype penetrance 10-24%.
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.
