Abstract
Description
Among the problems brought forth by Muller's discovery (1926-'27) of the production of gene-mutations and chromosome abnormalities by X-rays, was the question of the relative genetic effectiveness of the rays when applied at different stages of the germ cell history, and the related question of the possible influence of aging the mature germ cells, upon the production or detection of these variations. Conclusive data regarding both these questions in so far as they concern sex-linked lethal changes in the germ cells of the adult male Drosophila, have been secured by the present author, in a series of experiments conducted during the past sixteen months in the genetics laboratory of the University of Texas
