摘要：Conclusive proof that the mouse egg is capable of carrying out repair of genetic lesions present in the male genome was obtained through dominant-lethal studies of chemically treated spermatozoa and spermatids and through cytological analysis of first-cleavage metaphases. The maximum difference in repair capability between stocks of females, found for isopropyl methanesulfonate treatment, was large; considerably smaller differences were found for ethyl methanesulfonate, triethylenemelamine, and benzo[a]pyrene treatments; and no difference was found for x-ray treatment.
