In not02069 larvae, many R2-R5 axons fail to terminate in the lamina and instead project into the medulla.
In hemizygotes R1-R6 neurons project through the lamina and terminate in the medulla. A few appear to stop in the lamina. In the developing optic ganglia the regions of the outer proliferation centre (OPC) and lamina precursor cells (LPC) are closer together and the shape of the inner proliferation centre (IPC) is oval rather than round.

Excision of the P{PZ} element can revert the phenotype.
