**Exploring Meiosis: From Somatic Cells to Haploid Gametes** ------------------------------------------------------------ **I. Mitosis Recap** - **II. Reproduction: Asexual vs. Sexual** - **III. The Importance of Haploid Cells in Sexual Reproduction** - **IV. Advantages of Sexual Reproduction and the Role of Meiosis** - **V. Meiosis I: Separating Homologous Chromosomes** - **VI. Stages of Meiosis I** \* \*\*Overview\*\*: Provides an overview of the two rounds of cell division in meiosis, each comprising prophase, metaphase, anaphase, and telophase. \* \*\*Prophase I\*\*: Describes the events of prophase I, including chromosome condensation, nuclear envelope breakdown, synapsis, crossing over, and migration of centrioles. \* \*\*Metaphase I\*\*: Explains the unique alignment of homologous chromosome pairs (tetrads) along the metaphase plate and emphasizes the random orientation of these pairs, further contributing to genetic variability. \* \*\*Anaphase I\*\*: Discusses the separation of homologous chromosomes, with sister chromatids remaining attached, and contrasts this with the separation of sister chromatids in mitosis. \* \*\*Telophase I and Cytokinesis\*\*: Describes the events of telophase I, including chromosome migration to poles, nuclear envelope reformation, cytokinesis, and the resulting formation of two haploid daughter cells with non-identical sister chromatids due to crossing over. **VII.
