Summary x-rayed adult males ofDrosophila melanogaster were left with untreated females from 2 to 3 days after which the males were discarded. Sex-linked recessive lethals and translocations were scored in progeny produced during the first 2 or 3 days following irradiation, and after storage of the spermatozoa in the females for 6 days. The results obtained show that the frequencies of sex-linked lethals and of translocation involving the two large autosomes and the x-chromosome were unchanged by storage. In experiments in which Y, 2, 3 translocations were scored both the 2–3, and the Y translocations showed a slight increase. These experiments show that the strong storage effect on translocations produced by certain alkylating agents is peculiar to chromosomes treated by these chemicals.
