- Prophase I: Homologous chromosomes condense and pair up, forming tetrads; crossing over may occur.
- Metaphase I: Tetrads align at the metaphase plate; spindle fibers attach to each homologous chromosome.
- Anaphase I: Homologous chromosomes separate and move to opposite poles; sister chromatids remain attached.
- Telophase I (and cytokinesis): Two haploid daughter cells form, each with one set of chromosomes (still composed of two sister chromatids).
- Prophase II: Chromosomes re-condense in each haploid cell; nuclear envelope breaks down.
- Metaphase II: Chromosomes align individually at the metaphase plate in each cell.
- Anaphase II: Sister chromatids separate and move to opposite poles.
- Telophase II (and cytokinesis): Four genetically distinct haploid daughter cells form, each with a single set of unreplicated chromosomes.
