Question

Quizplus · Accepted Answer

The release of enzyme-rich granules from the egg that causes the separation of the vitelline envelope and the egg membrane is referred to as the cortical reaction. This reaction prevents polyspermy, which is the fertilization by more than one sperm, and facilitates the fusion of the haploid nuclei of the sperm and egg, leading to the formation of a zygote. Pronucleation and cytoplasmic localization occur after fertilization and are not related to the separation of the vitelline envelope and the egg membrane.
