What occurs when sperm cell unites with a egg cell?
When sperm reach an egg, there is a competition to get into the egg first. Since sperm travel in groups, theres a lot of competition. Once a sperm has penetrated the membrane, the membrane hardens, blocking the rest of the sperm out. Once inside, the sperm releases its genetic material, and the egg cell divides, and will continue so until a new baby is born.
