उत्तर
During oogenesis, each diploid cell produces one functional egg and three polar bodies.
Explanation:
- During oogenesis, a diploid primary oocyte undergoes meiosis I to produce one large secondary oocyte and a smaller polar body.
- The secondary oocyte undergoes meiosis II after fertilization to form one functional ovum and a second polar body.
- The first polar body may also divide to form two smaller polar bodies.
- Therefore, from one diploid cell, oogenesis results in one functional egg (ovum) and three polar bodies which are non-functional and eventually degenerate.
