Female mice from the C57Bl strain received 0, 50, or 200 R doses of whole-body x irradiation and were mated to control males from the same strain. Using an air-drying technique, the testes of the F/sub 1/ males were analyzed for the presence of chromosome rearrangements, but no translocation configurations were observed in the dividing spermatocytes of the 100 control males and of the 185 F/sub 1/ sons from irradiated females. Since meiotic preparations made one day after exposure of the females to x irradiation showed the presence of chromosome rearrangements in some first meiotic metaphases, it could be inferred that the absence of translocated offspring after maternal x ray exposure probably resulted from germinal selection.
