Cell Cycle and Cell Division — NEET/JEE Questions, Notes & Weightage
Covers the cell cycle phases (G1, S, G2, M), mitosis, and meiosis I/II in detail — chromosome behaviour at each stage is the dominant NEET question type. Meiosis specifically bridges directly into Class 12 Genetics, making this a chapter worth mastering rather than memorising.

Frequently asked questions
Mitosis or meiosis — which gets more NEET questions?
Meiosis, particularly the events of Prophase I (leptotene through diakinesis) and the genetic significance of crossing over, is tested more often and in more depth than mitosis.
What is the most commonly tested mix-up in this chapter?
Confusing the stages/features of meiosis I vs meiosis II, and mixing up which phase chromosome number actually halves (it is meiosis I, not II).
Why does this chapter matter for Class 12 Genetics?
Crossing over and independent assortment during meiosis are the physical basis for the inheritance patterns tested in Principles of Inheritance and Variation — understanding it here pays off twice.
