Flies are moderately sensitive to X rays.
Both premeiotic and meiotic magnification of rRNA sequences is inhibited in males.
Sterile. Homozygous larval brain ganglia have a reduced ability to synthesise DNA after exposure to N-acetoxy-2-acetylaminofluorene compared to wild-type.
Survival of homozygous and hemizygous larvae is hypersensitive to exposure to methyl methanesulfonate.
