The disjunction of chiasmata towards the ends of bivalent is called:

Options

A. Terminalization
B. Diakinesis
C. Interkinesis
D. Heteropycnosis

Answer

To answer the question, "The disjunction of chiasmata towards the ends of bivalent is called:", we can follow these steps:

### Step 1: Understand the Terms
- **Chiasmata**: These are the points where two homologous non-sister chromatids exchange genetic material during meiosis.
- **Bivalent**: This refers to a pair of homologous chromosomes that are aligned together during meiosis.

### Step 2: Identify the Process
- The process of disjunction refers to the separation of homologous chromosomes during meiosis. When chiasmata disjoin, it indicates that the exchange of genetic material is completed.

### Step 3: Recognize the Specific Term
- The specific term for the disjunction of chiasmata towards the ends of the bivalent is known as **Terminalization**. This is the process where the chiasmata move towards the ends of the chromosomes, leading to the separation of the homologous chromosomes.

### Step 4: Conclusion
- Therefore, the answer to the question is **Terminalization**.
