To ascertain the possible genetic effects of magnetic fields, the somatic reversion at the white locus and the somatic recombination mwh and fir genes in Drosophila melanogaster were examined quantitatively after lavae were exposed for 8 hours to static magnetic fields (8 T) or timevarying, sinusoidal magnetic fields (3.3 mT, 20 Hz). A static magnetic field of 8 T was effective in producing mosaic spots of eye color caused by intragenic mutation. The diagnosis according to statistical tests (Frei and Würgler, 1988) indicated a positive result under the testing conditions. Mosaic spots on the wing hairs caused by somatic recombination were slightly higher in the group exposed to static fields (8 T) than in the control group, but statistical analysis indicated a negative result. After exposure to time-varying magnetic fields (3.3 mT, 20 Hz), the mosaic spots of both types occurred with almost the same frequencies as in the control group.
