Genetic mapping information
Comments

This deletion removes a single ribosomal protein-coding gene (though other genes are also removed).

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

Df(1)JA26 hemizygous embryos exhibit head and thorax defects similar to tsg loss of function mutants.

With a very low penetrance, Df(1)JA26 hemizygous embryos show subtle defects in segmentation, including partial fusion of denticle band pairs in the register seen for Ten-m mutants.

Heterozygous P1 stage pupae have a significantly increased heart rate and an increased strength of heart beat rhythmicity compared to controls.

Does not cause unconditional lethality in hybrid females when heterozygous with D.simulans chromosome.

Initially showed maternal enhancement of dpphr4, but effect not due to disruption of discrete element within the deficiency.

Deficient embryos show an uninterpretable mutant midgut phenotype.

Homozygous embryos are very abnormal compared to wild-type.

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

No significant change in female lethality when in combination with Sxlf1.
