- Each primary spermatocyte undergoes two maturation divisions (Meiosis-I and Meiosis-II) and produces four sperms having half number of chromosomes.
- It is necessary to maintain the number of chromosomes constant from generation to generation.
- During Meiosis-I crossing over takes place which brings about variations.
Significance of Oogenesis:
- It produces haploid ovum.
- Polar bodies contain small amount of cytoplasm. It helps to retain adequate amount of cytoplasm in the ovum, which is essential for the development of early embryo.
