Gametogenesis and Maturation: The Formation of Eggs and Spermatozoa
The formation of the egg, in the ovary, is an extremely important period in ontogeny. It is much more than an accumulation of food material, which will be progressively utilized until the embryo becomes capable of feeding itself. It is also a period of intensive genetic activity, which leads to the synthesis of many important macromolecules (RNA, proteins) which will be used at later stages of development only.
