The stages of embryonic formation in the complexes can be divided into the following stages:
1- The stage of the formation of sexual cells (gametes), including:
The formation of sexual cells and the formation of male and female genitalia.
B) Producing sexual cells when the sexual growth of the individual is complete.
2. Fertilization: It is the union of the nucleus of the egg with the nucleus of the sperm to form the fertilized or unkempt egg or Zygote.
3. Cleavage The fertilization of the fertilized egg breaks several divisions resulting in a group of cells known as phlegates. Divisions continue until a mass of cells known as the bacterial mass forms.
4. The stage of the phallus or the plastula Blastula consists of a cavity within the microbial mass becomes a hollow ball the thickness of a single cell in the bowel or cavity in the animal pole, the thickness of several cells as in amphibians or in the form of a disk of cells floating on the surface known as a microbial disk as in reptiles The birds represent the rearrangement and distribution of cells according to what each set of cells will give in the future.
5 - the stage of lining or Gastroula Gastrula and lead to the differentiation of the three bacterial layers Actoderm and Mizoderm and Endoderm.
6. The organism and the formation of tissues and different organs represent the critical embryonic stage followed by the growth stage of these members.
7 - the stage of going out to life, whether from the egg as in fish, amphibians, reptiles, birds or birth as in mammals, a declaration of the completion of the composition and growth of most internal organs.
8. Puberty is the process of sexual maturity of the individual and means the complete organic and physiological growth of the organism.
