Processes in reproduction
- During breeding season, the germinal epithelium of ovary undergoes oogenesis and produces large number of ova, and thus the ovary gets folded.
- The germ cells (Stroma) present in ovarian follicles forms oogonium which finally converts to ova via primary and secondary oocytes and this process is known as oogenesis.
- The process of formation of Yolk in eggs is called vitellogenesis.
- The yolk is formed by vitellogenin (synthesis in liver in the presence of sex steroids), a calcium binding lipophosphoprotein.
