The process by which unfertilized egg develops into an individual is known as

Options

A. oogenesis
B. embryogenesis
C. parthenogenesis
D. spermatogenesis

Answer

**Step-by-Step Solution:**

1. **Understand the Question**: The question asks about the process in which an unfertilized egg develops into an individual.

2. **Identify the Options**: The options provided are:
- Oogenesis
- Embryogenesis
- Parthenogenesis
- Spermatogenesis

3. **Analyze Each Option**:
- **Oogenesis**: This is the process of formation and development of an oocyte (egg) in the female ovary. It involves the fertilization of the egg, so it does not answer the question.

- **Embryogenesis**: This refers to the development of a fetus from a zygote after fertilization. Since it starts with a fertilized egg, it is not relevant to the question.

- **Parthenogenesis**: This is a form of asexual reproduction where an unfertilized egg develops into a new individual. This process does not require fertilization and is the correct answer.

- **Spermatogenesis**: This is the process of producing sperm, which are male gametes. It does not relate to the development of an unfertilized egg.

4. **Conclusion**: Based on the analysis, the correct answer is **Parthenogenesis**, as it specifically describes the development of an individual from an unfertilized egg.

**Final Answer**: The process by which an unfertilized egg develops into an individual is known as **Parthenogenesis**.
