Other Comments
	The Df(2R)17l 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{w^var}KR3-2", a stable "brown-red" variant of the P{3'WP-2,w^var}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. (Mason et al., 2004)
