- 1. The Meiotic Cell Cycle By Leonard Zein
- 2. Interphase In the interphase of meosis, a sex cell begins to grow in size and prepare for growth.

- 9. Prophase I In the Prophase, the nucleolus begins to fade, and the chromatin begins to wind up into more tightly compacted chromosomes. The nuclear membrane eventually collapses.

- 14. Metaphase I In the metaphase, spindle fibres line up the chromosomes at the center of the cell.

- 16. Metaphase I
- 17. Anaphase I For the anaphase, the spindle fibers begin to shorten, causing the chromosomes to pull apart from each other.

- 29. Telophase I In the Telophase, nuclei form in each of the cells, and the chromosomes become less visible again. The two cells return to the interphase.

- 32. Interphase II
- 33. Interphase II The cells have returned to the interphase, and begin growing and preparing for growth.

- 36. Prophase II In the second prophase, the chromosomes become visible once again, the nucleus disappears, and spindle fibres begin reappearing.
- 37. Prophase II
- 38. Prophase II
- 39. Metaphase II Metaphase II consists of the spindle fibres aligning the chromosomes at the centre of the cells.

- 41. Metaphase II
- 42. Anaphase II In the second anaphase, the fibres begin pulling the chromosomes apart, each into two chromatids.
- 43. Anaphase II
- 44. Anaphase II
- 45. Cytokinesis II Cytokinesis occurs once again, and each cell begins to split once more.

- 53. TelophaseII The cells have finished dividing, each one now with a nucleus and half the number of chromosomes of the original cell. Nuclei have formed in each.
