NOT in combination with other aberrations
Heterozygosity for this deletion has no effect on the mutant ovarian phenotype of ovoD2.
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)64j chromosome acts as a dominant moderate 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.
