The correct option is (c).
Explanation
Meiosis is a specialized form of cell division that reduces the chromosome number by half, resulting in the production of haploid daughter cells. It is the fundamental process underlying sexual reproduction.
- Statement 1 is Incorrect: Unlike mitosis, which involves a single nuclear division, meiosis involves two sequential cycles of nuclear and cell division, known as Meiosis I and Meiosis II. Despite having two divisions, the DNA is replicated only once before Meiosis I.
- Statement 2 is Correct: At the end of Meiosis II, four haploid daughter cells are produced from a single diploid parent cell. In contrast, mitosis results in only two genetically identical daughter cells.
- Statement 3 is Correct: Meiosis occurs in the germ cells of sexually reproducing organisms to produce gametes (sperm and ova in animals; pollen and egg cells in plants). This reduction in chromosome number is essential so that the diploid number is restored upon fertilization.
Key Takeaway: Meiosis is defined by a double nuclear division that produces four haploid gametes, distinguishing it from mitosis which produces two diploid somatic cells.
