Significance of the perigametic interval as a major source of spontaneous mutations that result in mosaics.

Abstract excerpt

An earlier analysis showed that a significant percentage of spontaneous specific-locus mutations in mice are recovered as mosaics and that the spontaneous mutation rate per cell cycle is probably higher for those mutations that produce mosaics than for those that produce whole-body mutants. The finding that the average germline composition of the mosaics was approximately 50% supported the suggestion that...
