Flies are moderately sensitive to X rays.
Cells derived from homozygous embryos synthesise DNA at a reduced rate from an undamaged template compared to wild-type cells. Homozygous larval brain ganglia have a reduced ability to synthesise DNA from an undamaged template compared to wild-type.
Sensitive to 0.050% methyl methanesulfonate and sensitive to 0.008% HN2.
Larval survival hypersensitive to exposure to X rays (Oliveri, Harris and Boyd, 1990), methyl methanesulfonate and nitrogen mustard. Homozygotes fertile. Modified DNA synthesis (Boyd and Shaw, 1982).
mus307D1/mus307D1 has no effect on the frequency of X-Y chromosome nondisjunction seen in Df(1)X-1-53B males.
Separable from: ssar1.
Associated with a second unidentified mutagen-sensitive mutant allele.
