An increase in the rate of mutation was found in Drospolia melanogaster reared on a basic medium that was irradiated with a sterilizing dose (150,000 rads) of Co⁶⁰ gamma rays. In Muller-5 tests, sex-linked recessive lethals occurred only in the F₂ progenies of the male test flies obtained from breeding the parent fiies on irradiated medium, while visible changes occurred in experimental cultures from both the control and irradiated media. The frequency of sex-linked recessive lethals was 0.35, 0.55, and 0.8% in three independent experiments. Visible changes were two to six times more frequent in the irradiated series than in the controls.
