Abstract

Adult, male Drosophila melanogaster, heterozygous for 4 markers on each arm of the third chromosomes, were injected with ATP, exposed to 3000 r of X-rays, and backcrossed to the homozygous, recessive parent. Daily broods revealed crossover types in 9-15 days after irradiation. The frequency of radiation-induced crossovers was not affected by ATP, nor by post-treatment in N2 gas. Irradiation in N2, after N2 pretreatment, gave a significantly lower frequency of crossovers. Data from broods 10 and 11 contained no clusters and were used exclusively in evaluating the experiments.
