Genetic mapping information

This deletion removes multiple ribosomal protein-coding genes (in addition to other genes).

In combination with other aberrations

Transmission rate of Dp(1;f)J21A through females to progeny is 28%, Df(1)RK2 has no effect on transmission.

NOT in combination with other aberrations

The Fas2-positive longitudinal tracts are positioned farther apart from the midline than normal in mutant embryos.

Flies heterozygous for the deletion do not show a Minute bristle phenotype.

No second site non-complementing phenotype with zipEbr and zipmhc-c6.1.

Midgut development of mutant embryos is wild type.

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