Meiosis (Summary) • Meiosis is a type of cell division that occurs in sexually reproducing organisms. It involves two successive divisions, resulting in the formation of four haploid daughter cells, each with half the number of chromosomes as the parent cell. The key stages of meiosis include: • Prophase I: Chromosomes condense, and homologous pairs align and exchange genetic material through a process called crossing-over. • Metaphase I: Homologous chromosome pairs line up along the cell's equator. • Anaphase I: Homologous chromosomes are pulled apart and move to opposite poles of the cell. • Telophase I: Two haploid daughter cells are formed, each with a unique combination of genetic material. • Meiosis II: The two daughter cells undergo a second round of division, similar to mitosis, but with half the chromosome number. • Prophase II, Metaphase II, Anaphase II, and Telophase II: These stages lead to the formation of four haploid daughter cells, each genetically distinct. • Meiosis plays a crucial role in generating genetic diversity and ensuring the proper number of chromosomes in gametes for sexual reproduction. • #edutube #meiosis #thingyansane #biology
