Telophase II
Explanation:
The stages of meiosis are PMAT PMAT. It's like mitosis, but double the stages. Meiosis consists of meiosis I and meiosis II.
Prophase I
The nuclear membrane disappears. Chromatin condenses into chromosomes. Chromosomes find their homologous pair (synapsis) and form pairs (tetrads). They exchange DNA (crossover), creating genetic variety.
Metaphase I
The centrosomes extend spindle fibres, attaching to the chromosomes' middles (centromeres). The spindle fibres move the chromosomes.
Homologous pairs line up along the middle of the cell (equator or metaphase plate), with one chromosome on each side of the equator.
Anaphase I*
The cell is more like an oval (elongated). Spindle fibres pull the homologous pairs apart and to the opposite ends (poles) of the cell.
Telophase I*
The nuclear membrane reforms around chromosomes. There will be two cells, each with half of the original number of chromosomes (haploid).
Prophase II
The nuclear membrane disappears. The centrosomes clone themselves (replicate).
Metaphase II
The centrosomes extend spindle fibres, attaching to the chromosomes' centromeres. The fibres move the chromosomes to line up at the metaphase plate.
Anaphase II*
The cell is elongated. The spindle fibres pull the sister chromatids apart and towards the poles of the cell.
Telophase II*
The nuclear membrane reforms around chromosomes. There will be four cells in total, each with a haploid number of chromosomes.
*Cytokinesis, the division of the cytoplasm, occurs during around the anahases and telophases. It is not part of meiosis.
