Summary
The low dose of 0.2 mg/kg TEM allows the production of viable zygotes from the most sensitive stage of spermatogenesis. The frequency of translocations among offspring conceived during this peak period of sterility at 10–14 days p.i. is greater than among those conceived earlier, so that as the fertility of the treated males decreases (i.e. the percentage of dominant lethals increases) the frequency of translocations among their offspring increases. The results provide presumptive evidence that the spermatids are more sensitive to the mutagenic action of TEM than are the mature spermatozoa. A comparison of the incidence of translocations induced by TEM with that induced by X-rays is made and the significance of the occurrence of sterile animals among the F1 is discussed.
