Abstract

A heritable translocation test was carried out with acrylamide (AA) to obtain a dose-response relationship for induction of reciprocal translocations in late spermatids of the mouse. Male C3H/El mice were treated with single i.p. doses of 50 and 100 mg/kg of acrylamide and mated 7–16 days after treatment to untreated female 102/El mice. Translocation carriers among the F 1 progeny were selected by a sequential procedure of fertility testing and cytogenetic analysis including G-band karyotyping to determine the chromosomes involved in the respective translocations. The translocation frequencies observed with 50 mg/kg and 100 mg/kg of AA were 0.6% and 2.7%, respectively. The historical control translocation frequency was 0.04%. Doubling dose estimates based on these and previous data are discussed.
