[Radiosensitive Drosophila strains. IX. An analysis of the fertility and frequency of dominant lethal mutations in gamma-irradiated females of the mutant rad(2)201G1 strain].

Fertility and frequency of gamma-induced dominant lethals in female oocytes have been studied in a strain of Drosophila melanogaster carrying rad(2)201G1 mutation and in the wild type strain. It was shown that oocytes of the mutant strain exhibited the higher sensitivity during the whole period of oogenesis, as compared to those of the wild type flies. The strongest influence of rad(2)201G1 mutation on the frequency of dominant lethals and fertility was observed.
