Publisher's Synopsis
Excerpt from Second Report of the Michigan Academy of Science for the Year Ending June 30, 1900: Prepared Under the Direction of the Council
Fundamentally the sperm is not alone the energizing, it is the actual being that continues the race. The ovum is primarily but the bricks and mortar, as it were, that the sperm, the builder, employs in the construction of the house.
Coming, however, into such relation to this cell as to employ its machinery it necessarily is brought to the center and thus to the nucleus of the egg. Entangling this in its meshes, the female pro-nucleus is perforce incorporated in the plan. But the mechanism is not adapted to the utilization of so many chromosomes. There are twice as many as can be utilized by the ovular machinery. The remainder are therefore set aside, and, as only impedimenta in subsequent processes, are 'cast out as a second polar corpuscle. That this reducing division in both egg and sperm later occurs, by tachygenesis, before fertilization is but' an added safeguard to assure perfect cross-fertilization; for only thus can there be certainty of equal representation or, indeed, of one parent being at all represented in fertilization.
