...London's National Institute for Medical Research, "the possibility of an animal begetting progeny long after its death . . . We have also to realize that a similar possibility will exist for man ... It is one that will disturb deeply many who regard themselves as more than mere germ plasm containers.

Muller of Indiana University warned that even the peaceful use of atomic energy may kill off the human species by loading its germ plasm with too many "mutated" genes...
Usually it is "recessive." The altered recessive gene lurks in the germ plasm for generations, like an infinitesimal time bomb, waiting to combine with a similar gene in a cell of the opposite sex. Then, reinforced, it makes its influence felt. Theoretically, a mutation may be beneficial, but most of them are not. Some mutations kill the developing embryo. Some deform or otherwise handicap the young organism...
