On the Fractional- and Whole-body Mutations Induced by Soft X-rays in <i>Drosophila</i>

Abstract

a, b) and Yamasaki et al. (1963 a, b) found that in yeast cells, two types of mutation, fractional-and whole-colony, probably corresponding to the single-and double-strand change of DNA molecule, are induced by various mutagenic agents. High temperature, UV, X-rays, and chemicals such as hydroxylamine and acridine orange plus visible light are among those agents. In Drosophila similar
