How many primary oocytes are required to produce 200 ova in a human female?

Options

  1. A200
  2. B50
  3. C100
  4. D800

Correct answer

A. 200

Step-by-step solution

In oogenesis, meiotic division is unequal. A primary oocyte undergoes Meiosis I to form one large secondary oocyte and a tiny first polar body. The secondary oocyte then undergoes Meiosis II to form one large ovum (ootid) and a second polar body. Because of this unequal division, one primary oocyte yields only one functional ovum. Therefore, to produce 200 ova, exactly 200 primary oocytes are required. Answer: 200
