Detailed explanation-1: -The paired chromosomes line up along the equator (middle) of the cell. In metaphase II of meiosis II, it is sister chromatids that line up along the equator of the cell.
Detailed explanation-2: -Long protein filaments called kinetochore microtubules extended from poles on either end of the cell and attached to the kinetochores. During metaphase, the kinetochore microtubules pull the sister chromatids back and forth until they align along the equator of the cell, called the equatorial plane.
Detailed explanation-3: -Metaphase II: The paired chromosomes line up. Anaphase II: The chromatids split at the centromere and migrate along the spindle fibers to opposite poles. Telophase II: The cells pinch in the center and divide again.
Detailed explanation-4: -Metaphase II: During metaphase, each of the 23 chromosomes line up along the center of the cell at the metaphase plate.
Detailed explanation-5: -Answer and Explanation: The above statement, “Homologous pairs of chromosomes line up at the metaphase plate during metaphase II” is a true statement.
