This deletion removes a single ribosomal protein-coding gene (though other genes are also removed).
Fails to complement Df(2R)PC4, Df(2R)PC29 and Df(2R)P34, complements Df(2R)PclXM82, Df(2R)Pcl7B and Df(2R)Pcl11B.
Flies heterozygous for the deletion do not show a Minute bristle phenotype.
The Df(2R)PC66 chromosome acts as a dominant weak 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 a combination of nonsuppressing deficiencies and deficiencies with suppressors that map to the 2L tip.
