Meiosis is studied in smears of

Options

A. Developing anthers
B. Testes
C. Both A and B
D. Axillary buds

Answer

To answer the question "Meiosis is studied in smears of which of the following?" we need to analyze the options provided: developing anthers, testes, both A and B, and axillary buds.

### Step-by-Step Solution:

1. **Understanding Meiosis**:
- Meiosis is a type of cell division that reduces the chromosome number by half, resulting in the formation of gametes (sperm and eggs in animals, pollen and ovules in plants). It is also known as reductional division.

2. **Identifying the Locations of Meiosis**:
- Meiosis occurs in gamete-producing cells. In plants, meiosis takes place in the developing anthers where pollen grains (male gametes) are formed. In animals, meiosis occurs in the testes where sperm cells are produced.

3. **Analyzing the Options**:
- **Developing Anthers**:
- In plants, developing anthers are responsible for producing male gametes (pollen grains) through meiosis. Therefore, meiosis can be studied in smears of developing anthers.
- **Testes**:
- In animals, specifically in humans, meiosis occurs in the testes where spermatogonia undergo meiosis to produce haploid sperm cells. Thus, meiosis can also be studied in smears of testes.
- **Axillary Buds**:
- Axillary buds do not undergo meiosis as they are not involved in gamete production. Therefore, this option is not correct for studying meiosis.
- **Both A and B**:
- Since both developing anthers and testes are involved in meiosis, this option is correct.

4. **Conclusion**:
- The correct answer is **both A and B**, as meiosis can be studied in smears of both developing anthers and testes.

### Final Answer:
Meiosis is studied in smears of **both A (developing anthers) and B (testes)**.
