Textbook Question
Chapter 41, Problem 4CT
Occasionally more than one sperm penetrates and enters a human secondary oocyte. The result is formation of a multiple spindles and disruption of the first mitotic division. Explain why the presence of multiple sperm has this lethal disruptive effect.

In a possible future scenario, male fertility drops to zero,
