| Term | Definition |
|---|
| Meiosis I | 1. Prior to meiosis each chromosome is replicated. 2. Two new cells are produced which enter Meiosis II 3. Crossing over occurs. |
| Interphase I | Cells undergo a round of DNA replication, forming duplicate chromosomes |
| Prophase I | Each chromosome pairs with its corresponding homologous chromosomes to form a tetrad |
| Metaphase I | Spindle fibers attach to the chromosomes |
| Anaphase I | The fibers pull the homologous chromosomes toward opposite ends of the cell |
| Telophase I and Cytokinesis | Nuclear membrane forms. The cell seperates into two cells. |
| Meiosis II | 1. No replication. 2. Each entering cell has 2 chromatids. 3. Four haploid daughter cells produced. |
| Prophase II | Meiosis I results in two haploid (N) daughter cells, each with half the number of chromosomes as the original cell. |
| Metaphase II | The chromosomes line up in a similar way to the metaphase stage of mitosis. |
| Anaphase II | The sister chromatids separate and move toward opposite ends of the cell. Alleles segregate. |
| Telophase II and Cytokinesis | Meiosis II results in four haploid (N) daughter cells. |
