What you will learn in Dividing

1. 1. The cycle, to scale

   What fraction of a cell's life is spent dividing, computed from hours.

2. 2. Mitosis

   Two counters through a division, and the moment each one doubles.

3. 3. Meiosis, and where variation comes from

   Three sources of variation, each switchable, and the number that survives when one is off.

4. 4. Where the ratios come from

   Mendel's laws derived from chromosome behaviour rather than stated.

5. 5. When control fails

   Three checkpoints in series, and why one failure is not enough.
