The correct Answer is:
To solve the question regarding the minimum number of chiasmata in a bivalent, we can follow these steps: ### Step-by-Step Solution: 1. **Understanding Bivalent**: - A bivalent is formed during meiosis and consists of two homologous chromosomes that are paired together. Each homologous chromosome is replicated, resulting in two sister chromatids. 2. **Definition of Chiasmata**: - Chiasmata are the points where crossing over occurs between homologous chromosomes. This is the process of genetic exchange that contributes to genetic diversity. 3. **Minimum Chiasmata**: - In a bivalent, at least one chiasma is required for the homologous chromosomes to properly align and segregate during meiosis. This means that the minimum number of chiasmata in a bivalent is one. 4. **Conclusion**: - Therefore, the answer to the question is that the minimum number of chiasmata in a bivalent is **one**. ### Final Answer: The minimum number of chiasmata in a bivalent is **one**. ---
