![]() This results in an extra chromosome (n + 1) in two of the gametes and a missing chromosome (n - 1) in two of the gametes. Gametes are more commonly called sperm in. Students will cut out examples and glue them in the correct column. When a cell divides by way of meiosis, it produces four cells, called gametes. This activity provides a fun, engaging, and meaningful way to practice identifying characteristics of mitosis and meiosis. ![]() Crossing Over Metaphase The chromosomes pair up at the middle. When a cell divides by way of mitosis, it produces two clones of itself, each with the same number of chromosomes. Meiosis Flipbook By Noor Malikzada Meiosis 1 Prophase The homologous chromosomes pair up. ![]() If nondisjunction occurs in meiosis I, the homologous pair of chromosomes remain bound. There are two ways cell division can happen in humans and most other animals, called mitosis and meiosis. Nondisjunction may occur during meiosis I or meiosis II. \): Nondisjunction in Meiosis: Nondisjunction occurs when homologous chromosomes or sister chromatids fail to separate during meiosis, resulting in an abnormal chromosome number. ![]()
