lethal (with Df(2L)BSC258)
Only a small percentage of homozygotes survive to adulthood. These adult flies have a range of morphological defects. Larval neuroblasts contain polyploid figures.
Escapers have many missing bristles, behavioural defects and wings held out perpendicular to the body.
nebk05702 is a suppressor of phenotype of kniunspecified
I. Kiss.
Reversion analysis indicates that the adult and cell division phenotypes of the nebk05702 chromosome are caused by the P{lacW} element insertion. fokHN237 does not rescue the phenotype of flies homozygous for the nebk05702 mutation, indicating that the phenotypes associated with this mutation are due to the P{lacW} insertion disrupting the neb gene, and are not due to disruption of the fok gene.
