The wing discs of mei-41unspecified mutant third instar larvae exhibit similar levels of apoptosis to controls in response to X-ray induced irradiation. As in controls, very little apoptosis is seen in the absence of irradiation.
Mutants can be recombination defective. Mutants can show sensitivity to methyl methanesulfonate, nitrogen mustard, UV light, γ rays or X rays. Mutants are not defective in repair of single strand breaks or excision repair, but can be defective in post-replication repair.
