Studies on chemical induction of chromosomal aberrations in postcopulation germ cells and zygotes of female mice. II. Induction of heritable translocations.

Abstract
The induction of heritable translocations with chemicals in postcopulation germ cells of female mice was investigated. In the methyl methanesulfonate (MMS)-treated group (100mg/kg), 14 partially sterile and 5 sterile males out of 118 F1 male progeny were found. In contrast, in the mitomycin C (MC)- treated group (3mg/kg and 4mg/kg) the frequencies were low. These results indicate that the yield of heritable translocations parallels the formation of chromosome-type aberrations at the first cleavage reported previously.
