Four different genotypes of Drosophila melanogaster were x irradiated at 1350 r during the first, second, and third larval instars. Treatment with x rays resulted in a threefold increase in the frequency of somatic crossing over, evidenced by incidence of abdominal mosaicism. This effect was influenced by genotype and the ontogenetic time at which irradiation occurred. No mosaic spots were detected in the wings, even after irradiation. It is concluded that if somatic crossing over occurs in the wing aulage, it does so at an extremely low frequency. (auth)
