The correct Answer is:
To solve the question "If meiosis occurs inside pollen grain and egg nuclei, it will be?", we can follow these steps: ### Step 1: Understand the Types of Meiosis We need to recognize the different types of meiosis: - **Zygotic Meiosis**: This occurs in the zygote after fertilization, leading to the formation of haploid cells from a diploid zygote. - **Gametic Meiosis**: This occurs during the formation of gametes (sperm and egg cells), resulting in haploid gametes. - **Sporic Meiosis**: This occurs during the formation of spores, leading to the production of haploid spores. ### Step 2: Identify the Context of the Question The question specifically mentions "pollen grain" and "egg nuclei". Pollen grains are the male gametes in plants, and egg nuclei are the female gametes. Therefore, we are dealing with the formation of gametes. ### Step 3: Relate the Context to the Types of Meiosis Since pollen grains and egg nuclei are gametes, the type of meiosis that occurs to form these gametes is **gametic meiosis**. This is because gametic meiosis is responsible for producing haploid gametes necessary for fertilization. ### Step 4: Choose the Correct Option Based on the analysis, the correct answer to the question is **B: gametic meiosis**. ### Final Answer If meiosis occurs inside pollen grain and egg nuclei, it will be **gametic meiosis**. ---
