Comment:

Scer\FRT-mediated recombination between the two progenitor insertions has resulted in the deletion of the genomic sequence between them.

Detailed Description
Statement
Reference

Mutants are viable but flightless and extend their wings abnormally. Maternally and zygotic mutant animals are also viable but survival rates are reduced. The length of the ventral nerve cord is not extended in zygotic or maternal/zygotic mutants.

Mutants show abnormal larval migratory behaviour, crawl slower than wild type, and do not recover and walk properly in a 'RING assay'. Head sweeping behaviour is abnormal.

Statement
Reference

In contrast to either single mutant, noloΔ4-12 Oatp30BΔ2-14 double mutants show dramatically reduced rates of eclosion and female sterility. The ventral nerve cord is shaped normally in double mutants. Head sweeping behaviour in double mutant larvae is dramatically reduced compared to either single mutant.
