Fertilization: How the Sleeping Egg Awakes

Part of the Heidelberg Science Library book series (HSL)


Fertilization of the egg is an all-important event for the life of all organisms that reproduce sexually. Not only does it start the machinery for embryonic development, but it also has fundamental genetic consequences: the diploid (2n) state is restored and the paternal hereditary characters are introduced into the fertilized egg (also called the zygote). In most species, the sex of the future adult is established at fertilization.
