Comments on Cytology
	The left Df(2L)J2 breakpoint lies within CG5731 or CG5727 or in the region between them, and lies in the range 2L: 10208117..10210314 (R5) (predicted cytology: 31B1). (Yamamoto et al., 2009.12.23) The right Df(2L)J2 breakpoint likely lies within CG31869, CG18561 or Nos or in the region between these genes, and lies in the range 2L: 10792442..10804501 (R5) (predicted cytology: 32B1).

Phenotypic Data
In combination with other aberrations	Df(2L)J2/+ heterozygotes show full suppression of In(1)w^m4 variegation. (Sinclair et al., 1992)
NOT in combination with other aberrations	The Df(2L)J2 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{w^var}KR3-2", a stable "brown-red" variant of the P{3'WP-2,w^var}2Lt insertion). (Mason et al., 2004) Acts as a dosage sensitive maternal modifier of run: causes tergite defects in greater than 50% of run³ heterozygotes. (Duffy et al., 1996) Heterozygosity for this deletion has no effect on the mutant ovarian phenotype of ovo^D2. (Pauli et al., 1995) Lethal over da

	Replication proceeds but there are fewer larger nuclei. (Smith et al., 1993) The original Df(2L)J2 chromosome also carried an additional deletion within polytene region 22. (Sinclair et al., 1992)
