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.
Heterozygotes are moderately sensitive to ionising radiation compared to control flies.
Df(3L)GN24 embryos show defects in tracheal cell migration within specific metameres.
The Df(3L)GN24 chromosome does not act as a dominant suppressor of telomeric silencing (assayed using the effect of the chromosome on the eye colour phenotype of flies carrying "P{wvar}KR3-2", a stable "brown-red" variant of the P{3'WP-2,wvar}2Lt insertion).
Heterozygosity for Df(3L)GN24 results in 13.1% X chromosome nondisjunction and 7.3% fourth chromosome nondisjunction in In(1)FM7/X ; svspa-pol females.
Homozygous embryos have abnormal gut morphology; visceral mesoderm cells do not migrate dorsoventrally and dorsal midgut closure fails.
Weak second site non-complementing phenotype with zipEbr and zipmhc-c6.1 : malformed phenotype penetrance 10-24%.
Shows no maternal enhancement of dpphr4.
Shows a dose-sensitive interaction with pbhs.PB.
Deficient embryos show an uninterpretable mutant midgut phenotype.
The left Df(3L)GN24 breakpoint lies within Eip63F-1 or Eip63F-2 or in the region between them, and lies in the range 3L:3910034..3935268 (R5) (predicted cytology: 63F6-63F7).
The right Df(3L)GN24 breakpoint lies within shep and perhaps also within the intronic gene CG4669 in the range 3L:5177885..5228896 (R5) (predicted cytology: 64C8-64C9).
