Ninja Bodyguards protect it!
NO!!!! There are no such thing as ninja bodyguards, although there are guard cells in plant cells but that is not what I'm answering.
Multiple fertilization normally doesn't happen because the fluids secreted by the vagina are acidic(means they have a low ph) and destroy most sperm.
This all true but what really stops multiple sperm from fertilizing an egg is two things. One is at the tip of the sperm is a chemical that when it touches the outer layer of the egg it changes the polarity of the egg making it impossible for another sperm to fertilize. Also you can have multiple fertilization. It caused chiral people I think. Meaning people with patches of different genetic code in their bodies.
