Oogenesis
For each cycle only one ova is produced. Along side this 2 or 3 polar bodies are produced as well. Ova's are much larger in comparison to sperm.
Total Process
Spermatogenesis
Location
The cells divide equally.
Number of meiotic divisions
Occurs in the testes.
Is Germ line epithelium involved?
It is involved in the production of the gametes
Oogenesis
Number of meiotic divisions
The cytoplasm is not evenly distributed.
Location
Primarily in the ovaries but sometimes in the ovaduct.
Is Germ line epithelium involved?
