hide 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).
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).

hide Phenotypic Data
In combination with other aberrations
Df(2L)J2/+ heterozygotes show full suppression of In(1)wm4 variegation.
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{wvar}KR3-2", a stable "brown-red" variant of the P{3'WP-2,wvar}2Lt insertion).
Acts as a dosage sensitive maternal modifier of run: causes tergite defects in greater than 50% of run3 heterozygotes.
Heterozygosity for this deletion has no effect on the mutant ovarian phenotype of ovoD2.

Replication proceeds but there are fewer larger nuclei.
The original Df(2L)J2 chromosome also carried an additional deletion within polytene region 22.
