Chromosomes line up along the equator
Web20 ian. 2024 · The chromosomal pairs line up along the cell's equator, known as the metaphase plate, with the help of these microtubules. The pairing of each maternal chromosome with its corresponding paternal chromosome occurs during meiosis. A typical female has 23 homologous chromosomes, compared to a typical male's 22. Web6 iul. 2024 · Anaphase I begins when homologous chromosomes separate. The nuclear envelope reforms and nucleoli reappear. The chromosomes coil up, the nuclear membrane begins to disintegrate, and the centrosomes begin moving apart. Spindle fibers form and sister chromatids align to the equator of the cell.
