Comments

Deletion of sequences from 0 to approximately 34kb (coordinates with respect to proximal end of a cloned l(2)gl region, close to the tip of 2L).

(Mechler et al., 1985)

DNA coordinates, with respect to origin at tip of 2L: 34.7

Comments on Cytology

32kb deletion that deletes the entire l(2)gl gene and some adjacent proximal sequences.

(Opper et al., 1987)

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
    NOT in combination with other aberrations

    Homozygous lethal. Mutant phenotype rescued by P{l(2)gl-15}.

    (Opper et al., 1987)

    weak allele: brain and discs are small and rudimentary and grow slowly in transplants. Lethal phase: larvae 81.4%, pupae 18.6%
