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.

Other Comments

Df(2L)ast1 as reported is necessarily haplolethal due to deletion of dpp. The original isolation may have included a transposition of some or all of the deleted region. Many studies that have reported haploviabiity of Df(2L)ast1 have probably in fact used a mis-labelled stock of Df(2L)ast2.
