• Effects of x-irradiation upon bristle numbers in Drosophila were remarkable for increasing variances but none of increase or decrease was observed for the means. This suggests that the chaeta characters in Drosophila are controlled by neutral genes and the cause of variance increase must be due to induced polygenic mutations.The doubling doses for polygenes involving the chaeta characters were estimated by the two different methods, i.e., isogenisation and selection. They are estimated to be 58r and 29r respectively for abdominal and sternopleural bristle numbers from the isogenisation experiment and to be 18r on an average from selection experiments, providing the spontaneous variance increase rates of the traits be 0.005 and 0.001per generation, respectively.
