The Polar Body Formed After Meiosis I Becomes the Egg

Question

The polar body formed after meiosis I becomes the egg cell.

Accepted Answer

The polar body formed after meiosis I does not become the egg cell. Instead, the egg cell is formed after the completion of meiosis II, when the secondary oocyte undergoes further division to become a mature egg cell. The polar body formed during meiosis II is usually much smaller than the first polar body and eventually disintegrates.
