Meiosis explorer
Contrast reductional and equational divisions without claiming every substaging detail is shown.
What this explorer teaches
Educational overview of meiosis I/II, homolog pairing, and separation.
Learning goal: Highlight ploidy reduction and variation (crossing over + independent assortment) at overview depth.

How to use this explorer
- Advance with Next / Previous, the step chips, or keyboard ← →.
- On touch devices, tap chips and buttons (minimum comfortable target size).
- If you prefer reduced motion, the site respects
prefers-reduced-motionand jumps between states without animation. - Screen-reader / keyboard users: focus stays on controls; the live region announces the current step.
Scientific notes & limits
After one replication, meiosis I separates homologs (reductional) and meiosis II separates sisters (equational). Crossing over and independent assortment generate variation. Substages (leptotene, zygotene, etc.) are omitted for clarity at overview depth.
