# Meiosis Meiosis is a type of cell division that occurs in eukaryotic organisms, such as mammals. It results in the production of gametes (e.g., sperm and egg cells) with half the number of chromosomes compared to the parent cell. This is a reduction division. In humans, meiosis starts from a diploid (2n) cell containing 46 chromosomes, and it results in haploid (n) cells, each carrying 23 chromosomes. Meiosis consists of two stages: ## Meiosis I * **Interphase**: (2n → 4n) * **Prophase I**: (4n) * **Metaphase I**: (4n) * **Anaphase I**: (2n + 2n) * **Telophase I**: (2n + 2n). ## Meiosis II * **Interphase II**: (2n → 2n). This phase may or may not occur between meiosis I and II. * **Prophase II**: (2n) * **Metaphase II**: (2n) * **Anaphase II**: (n + n) * **Telophase II**: (n + n) Each of the four resulting cells has only one copy of each chromosome (haploid), creating genetic variation. The image illustrates the process visually. **Important Note:** The graphic shows the stages of meiosis and how homologous chromosomes pair. It highlights that homologous chromosomes are separated during Meiosis I, and sister chromatids are separated during Meiosis II. This leads to four genetically diverse haploid cells. The diverse arrangements of homologous chromosomes during metaphase I contribute to the genetic diversity of gametes.
