Affected Genes Inferred by Location (0)

If no genes are listed here, it may be because the affected region is very large. The JBrowse insert above may show an error for the same reason, and other FlyBase tools such as CytoSearch may also fail for large regions. You can contact FlyBase for more help.
In these cases, there will be no "Export to Hitlist" button to the left.

Phenotypic Data

In combination with other aberrations

No effect on In(1)w^m4h position-effect variegation.

(Wustmann et al., 1989)

NOT in combination with other aberrations

Flies heterozygous for the deletion do not show a Minute bristle phenotype.

(Marygold et al., 2007)

The Df(2L)N22-5 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).

(Mason et al., 2004)

Heterozygosity for Df(2L)N22-5 results in 0.4% X chromosome nondisjunction and 0.0% fourth chromosome nondisjunction in In(1)FM7/X ; sv^spa-pol females.
