The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding the Phases of Meiosis:** - Meiosis consists of several phases, including Leptotene, Zygotene, Pachytene, Diplotene, and Diakinesis. Each phase has distinct characteristics related to chromosome behavior. 2. **Identifying the Leptotene Phase:** - In the Leptotene phase, chromosomes begin to condense and become visible, but homologous chromosomes do not yet pair. 3. **Recognizing the Zygotene Phase:** - During the Zygotene phase, homologous chromosomes start to pair up. This pairing is crucial for the formation of the synaptonemal complex. 4. **Formation of the Synaptonemal Complex:** - The synaptonemal complex is a protein structure that forms between homologous chromosomes during the Zygotene phase. It facilitates the pairing of homologous chromosomes and the formation of a tetrad. 5. **Conclusion:** - The synaptonemal complex becomes visible at the end of the Zygotene phase. Therefore, the answer to the question is that the synaptonemal complex is visible from the Zygotene phase. **Final Answer:** The synaptonemal complex is visible from the Zygotene phase. ---
