I keep getting “Gametogenesis” questions wrong in Human Reproduction & Reproductive Health. What's the trap?

thinking oogenesis produces four functional eggs like spermatogenesis makes four sperm.

The usual trap: thinking oogenesis produces four functional eggs like spermatogenesis makes four sperm. How to avoid it: oogenesis → 1 ovum (the rest are polar bodies); spermatogenesis → 4 sperm. Go back to the definition — the formation of gametes — spermatogenesis makes four sperm per cell, oogenesis makes one ovum plus polar bodies.

Key point

Gametogenesis

Common mistake

thinking oogenesis produces four functional eggs like spermatogenesis makes four sperm.

Memory tip

oogenesis → 1 ovum (the rest are polar bodies); spermatogenesis → 4 sperm.
