The monofunctional ethylating agent EMS has been found to induce ts lethal mutations in Drosophila melanoqaster. Temperature sensitive lethals can be induced on both the X and the second chromosomes. The frequencies of ts lethal induction with respect to the estimated number of "single hit" lethal mutations are not significantly different (for the X chromosome 12.5% and for the second, 10.9%). The ts lethals from each chromosome have similar visibilities at high and low temperatures. As with the ts lethals on the X chromosome, Suzuki et al, 1967) those on the second behaved in a manner compatible with the suggestion that Drosophila ts lethals are similar to those found in micro-organisms. These mutants, particularly dominant ts lethals, may provide powerful tools for Drosophila genetic investigation. / Science, Faculty of / Zoology, Department of / Graduate
