The correct Answer is:
### Step-by-Step Solution: 1. **Understanding Apomixis**: - Apomixis is a type of asexual reproduction found in some plants. It allows for the formation of seeds without the process of fertilization. This means that the seeds can develop without the fusion of male and female gametes. 2. **Assertion Analysis**: - The assertion states that "Apomixis is a form of asexual reproduction that mimics sexual reproduction." This is true because, although apomixis does not involve fertilization, it produces seeds that can give rise to new plants, similar to how seeds are produced in sexual reproduction. 3. **Reason Analysis**: - The reason given is "In apomixis there is formation of seed without fertilization." This statement is also true. In apomixis, the embryo develops from the egg cell through mitosis, bypassing the need for fertilization. 4. **Connecting Assertion and Reason**: - The reason provided explains the assertion. Since apomixis involves the formation of seeds without fertilization, it supports the idea that it mimics sexual reproduction by producing seeds, even though the process is asexual. 5. **Conclusion**: - Both the assertion and the reason are true, and the reason correctly explains the assertion. Therefore, the correct answer is that both statements are true, and the reason is the correct explanation for the assertion. ### Final Answer: Both the assertion and the reason are true, and the reason is the correct explanation for the assertion. ---
