Genetic information is transferred from zygote to all body cell by:-

Options

A. Meiosis
B. Amitosis
C. Endomitosis
D. Mitosis

Answer

To answer the question "Genetic information is transferred from zygote to all body cells by:", we will analyze the options provided and identify the correct process involved in the transfer of genetic information.

### Step-by-Step Solution:

1. **Understanding the Zygote**:
- The zygote is the initial cell formed when a sperm cell fertilizes an egg cell. It contains a complete set of genetic information, which will be passed on to all body cells as the organism develops.

2. **Identifying the Processes**:
- We need to evaluate the processes mentioned in the options: Meiosis, Amytosis, Endomytosis, and Mitosis.

3. **Evaluating Meiosis**:
- Meiosis is a type of cell division that reduces the chromosome number by half and is essential for the formation of gametes (sperm and egg cells). It does not transfer genetic information from the zygote to body cells.
- **Conclusion**: Meiosis is **not** the correct answer.

4. **Evaluating Amytosis**:
- Amytosis is a form of cell division that occurs without the formation of spindle fibers and does not involve the typical stages of mitosis. It is not a common method of cell division in multicellular organisms.
- **Conclusion**: Amytosis is **not** the correct answer.

5. **Evaluating Endomytosis**:
- Endomytosis refers to the replication of chromosomes without subsequent nuclear division, leading to an increase in chromosome number within a cell. This process does not contribute to the transfer of genetic information from the zygote to body cells.
- **Conclusion**: Endomytosis is **not** the correct answer.

6. **Evaluating Mitosis**:
- Mitosis is the process of cell division that results in two daughter cells, each having the same number of chromosomes as the parent cell. It is responsible for the growth and development of the organism, allowing the genetic information from the zygote to be distributed to all body cells.
- **Conclusion**: Mitosis is the correct answer.

7. **Final Answer**:
- The genetic information is transferred from the zygote to all body cells by **mitosis**.
