A dominant lethal mutation, occurring in the male germinal cell, may lead to the inability of the affected cell to fertilize an egg or, once having fertilized, to the failure of development beyond the blastocyst stage (implantation).

The federal plan proposes a cooperative effort with the provincial governments to establish criteria for plant siting; to develop standards for the necessary equipment, in strumentation, and operating conditions; and to initiate negotiations leading io (he designation of a number of regional disposal facilities across Canada.
