Process which is antithetical to fertilization is

Options

A. Mitosis
B. Meiosis
C. Vegetative propagation
D. Apomixis

Answer

To solve the question "Process which is antithetical to fertilization is:", we need to understand the processes involved in fertilization and how they relate to the options given: mitosis, meiosis, vegetative propagation, and apomixis.

### Step-by-Step Solution:

1. **Understand Fertilization**:
- Fertilization is the process where two haploid gametes (sperm and egg) fuse to form a diploid zygote. This is a key reproductive process in sexual reproduction.

2. **Analyze the Options**:
- **Mitosis**: This is a type of cell division where a single parent cell divides to produce two identical diploid daughter cells. It does not involve the fusion of gametes, so it is not directly opposite to fertilization.
- **Meiosis**: This is a specialized type of cell division that reduces the chromosome number by half, producing four haploid gametes from a diploid cell. It is the process that generates the gametes involved in fertilization, making it antithetical to the process of fertilization itself.
- **Vegetative Propagation**: This is an asexual reproduction method where new plants grow from parts of the parent plant. It does not involve gametes or fertilization.
- **Apomixis**: This is also an asexual reproduction method where seeds are produced without fertilization. Like vegetative propagation, it does not involve the fusion of gametes.

3. **Identify the Antithetical Process**:
- Among the options, meiosis is the only process that is antithetical to fertilization because it produces haploid gametes that are involved in the fertilization process, while fertilization itself is the fusion of these gametes to form a diploid zygote.

4. **Conclusion**:
- Therefore, the process which is antithetical to fertilization is **meiosis**.

### Final Answer:
Meiosis
