Mutations were induced in Drosophila males by tritiated thymidine fed to larvae or injected into adults. Radioautographs of testes of treated males demonstrated a correlation between the occurrence of mutations and the presence of labeled sperna bundles. In addition to the presence of sex-linked recessive lethals, dominant lethals were also measureable. Mapping of the induced sex- linked recessive lethals disclosed a nonrandom distribution which differed from reported distributions of mutations induced by x rays and gamma rays. Distribution of mutations induced by H/sup 3/T appears to reflect the varying frequency with which thymine bases occur along the lengih of the Drosophila X chromosome. (auth)
