In animals, meiosis comes
- A) after fertilization
- B) after every mitotic division
- C) before fertilization
- D) before every mitotic division
Correct Answer: D) before every mitotic division
Explanation
This question is asking about where meiosis occurs in animals. Meiosis is a type of cell division that produces sex cells, such as sperm and eggs. The question is asking when this process occurs in animals. Option A suggests that meiosis occurs after fertilization. This is incorrect because fertilization occurs when a sperm cell and an egg cell join together to form a zygote, which then undergoes mitotic divisions. Option B suggests that meiosis occurs after every mitotic division. This is also incorrect because mitosis and meiosis are two different types of cell division. Mitosis produces two identical daughter cells, while meiosis produces four non-identical daughter cells. Option C suggests that meiosis occurs before fertilization. This is the correct answer because meiosis is the process that produces the haploid gametes (sperm and egg cells) that combine during fertilization to form a diploid zygote. Option D suggests that meiosis occurs before every mitotic division. This is incorrect because mitotic divisions produce identical daughter cells, while meiosis produces non-identical daughter cells. Option E suggests that meiosis occurs during fertilization. This is also incorrect because meiosis occurs before fertilization, not during it. In conclusion, the correct answer is option C: before fertilization. Meiosis is the process that produces haploid gametes before they combine during fertilization to form a diploid zygote.
