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.

In combination with other aberrations

NOT in combination with other aberrations

The Df(2L)fn5 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).
