Question

During oogenesis, each diploid , primary oocyte produces

• A. four functional sperms
• B. two functional eggs and two polar bodies
• C. four functional polar bodies
• D. one functional egg and three polar bodies

Answer 1

Answer: (D)

one functional egg and three polar bodies

Answer 2

Oogenesis is the process of formation of a mature female gamete (ovum). During oogenesis, each diploid primary oocyte (formed by mitotic divisions of oogonia or egg mother cells) undergoes two maturation divisions.? In the first meiotic division, the primary oocyte divides into two very unequal haploid daughter cells - a large secondary oocyte and a very small first polar body or polocyte. In the second maturation division the first polar body may divide to form two second polar bodies. The secondary oocyte again divides into unequal daughter cells, a large ootid and a very small second polar body. The ootid grows into a functional haploid ovum. Thus from one primary oocyte, one ovum and three polar bodies are formed. The ovum is the actual female gamete.
