Genetic mapping information
Comments
This deletion removes a single ribosomal protein-coding gene (though other genes are also removed).
Right breakpoint around 12.5 kb in 35C walk of Lasko and Ashburner (1988, Nature 335: 611-17)

Phenotypic Data
In combination with other aberrations
Weakly suppresses the zeste phenotype in a z1 w11E4; Tp(1;2)TE35B homologue.
No effect on In(1)wm4h position-effect variegation.
NOT in combination with other aberrations
Flies heterozygous for the deletion do not show a Minute bristle phenotype.
Chromosome acts as a weak trans-suppressor of a physical interaction between tandemly duplicated copies of w+, an interaction that is required for the suppression of genes by z1.

Other Comments
 
The Df(2L)fn30 chromosome acts as a dominant strong 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), but this is a false positive result (the suppressor is not within the bounds of the deficient region) because the region of the deficiency is covered by one or more nonsuppressing deficiencies.
