Compare and contrast the similarities and differences between the PROCESSES of spermatogenesis and oogenesis.
Difference between spermatogenesis and oogenesis-
Feature | Spermatogenesis | Oogenesis |
---|---|---|
Definition | Production of sperms from spermatogonia | Production of eggs from oogonia |
Organ involved | Testes | Ovary |
Time of development | This occurs after puberty till death. It is a continuous process | Primary oocytes are formed in utero. Completion of first meiotic division takes place after ovulation and secondary meiosis occurs after fertilization |
Number of gametes formed | Four gametes are produced by a single primary spermatocyte | Single primary oocyte gives rise to a secondary oocyte and a polar body( that is discarded ) after completion of meiosis 1. |
