Question

$1^{st}$ polar body is formed at which stage of oogenesis?

• A. Meiosis $I$
• B. Mitosis $I$
• C. Differentiation
• D. None of these

Answer 1

Answer: (A)

Meiosis $I$

During the maturation phase of oogenesis, primary oocyte undergoes first meiotic division and forms two haploid daughter cells - large secondary oocyte and a small first polar body.

This small first polar body dies after that.

So, the correct answer is A.
