The increase in x-ray induced rate of recessive sexlinked lethals in Drosophila melanogaster by feeding ironsaccharate, reported previously, has led to some far reaching conclusions about the participation of indirect mechanisms in the radiation induced mutation process. However, in large scale experiments the effect was not reproduced. Some of the tests represented an exact repetition of tbe former genetical and radiation procedures, in others further parameters (translocations, state of maturity of the irradiated germ cells, feeding of ferrousgluconate) were considered. A certain factor of the genetical technique, representing a neglect of the dependence of the mutation rate on the state of maturity of the irradiated germ cells, is experimentally shown to be the probable cause of that discrepancy. Consequently, the speculations based on the earlier results seem to require reconsideration. (auth)
