During which stage of cell division is the number of chromosomes reduced by half?

✅Explanation:
The number of chromosomes is reduced by half during Meiosis-I. This stage is crucial for sexual reproduction and involves two rounds of division (Meiosis I and Meiosis II). During Meiosis I, homologous chromosomes are separated into different cells. As a result, the diploid cell (2n) divides to produce two haploid cells (n), effectively halving the chromosome number. This reduction is essential for maintaining the species' chromosome number through generations during fertilization.

📌 Other Options Explanations:
Option A: Mitosis – Mitosis is a type of cell division that results in two genetically identical diploid daughter cells. It does not reduce the chromosome number; instead, it maintains it. Mitosis is primarily responsible for growth, repair, and asexual reproduction in organisms.
Option C: Meiosis-II – Meiosis-II is similar to mitosis and does not reduce the chromosome number further. Instead, it separates sister chromatids, resulting in the production of four haploid cells from the two haploid cells formed during Meiosis I. The chromosome number remains haploid (n) after this stage.
