This deletion removes a single ribosomal protein-coding gene (though other genes are also removed).
Inferred to overlap with: Df(2R)X58-5.
Flies heterozygous for the deletion do not show a Minute bristle phenotype.
The Df(2R)59AD 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(2R)59AD results in 1.5% X chromosome nondisjunction and 0.0% fourth chromosome nondisjunction in In(1)FM7/X ; svspa-pol females.
Homozygous embryos older than about stage 12 are not detected, presumably due to lethality before this stage. The anterior mesoderm of homozygous embryos lacks hemocytes.
This complementation data was intended to describe Df(2R)59AB but "Df(2R)59AD" was written in error: see Brown, 1999.2.14, pers. comm.
