| Abstract: | A third chromosome mutator gene effectively increases the spontaneous frequency of sex-linked recessive lethals in females but not in females of Drosophila melanogaster. Approximately half the mutator-induced mutants occur as clusters of the same mutant implying a premeiotic origin. An appreciable number of the mutator-induced lethals are associated with comparatively long deficiencies of several salivary gland chromosome bands. The possible modes of mutator gene action are conjectured. |
