Thelytoky occurs in

Options

A. Aphids
B. Typhlina
C. Honey Bee
D. Wasp.

Answer

**Step-by-Step Solution:**

1. **Understanding Thelytoky**: Thelytoky is a form of parthenogenesis where females are produced from unfertilized eggs. This means that the offspring are genetically identical to the mother.

2. **Identifying Organisms**: The question asks which organism exhibits thelytoky. We have four options:
- A. Aphids
- B. Typhelana
- C. Honeybee
- D. Wasp

3. **Analyzing Each Option**:
- **Aphids**: Known to reproduce through thelytoky, particularly in certain species where females can produce offspring without fertilization.
- **Typhelana**: Less commonly known and not typically associated with thelytoky.
- **Honeybee**: Honeybees have a complex reproductive system involving fertilized and unfertilized eggs, but they do not primarily reproduce through thelytoky.
- **Wasp**: Some wasps exhibit parthenogenesis, but thelytoky is not a common reproductive strategy for them.

4. **Conclusion**: Based on the analysis, the organism that primarily exhibits thelytoky is **Aphids**.

5. **Final Answer**: The correct answer is **A. Aphids**.
