title: [Radiosensitivity of Drosophila lines. VII. The effect of the maternal genotype on the yield of recessive and dominant lethal mutations induced by the gamma irradiation of males].
abstract: The effect of material repair on induction of paternal mutations was tested with radiosensitive rad(2)201G1 mutant. Basc males were irradiated at doses from 0 to 60 Gy of gamma-rays and mated to the radiosensitive mutant or control females. Frequencies of sex-linked recessive lethals and dominant lethals (induced in the paternal genome) were determined. With control females, the rate of recessive lethals increased linearly from 0 to 60 Gy. With rad(2)201G1 mutant, an increase in spontaneous and induced rates of paternal dominant lethals was observed; the rate of sex-linked recessive lethals increased non-linearly from 0 to 60 Gy.
