Detailed explanation-1: -During metaphase I, all of the doubled homologous chromosome pairs line up along the midline of the cell between the two centrioles. During anaphase I, the homologous chromosome pairs separate and are pulled to opposite poles of the cell by spindle fibers attached to the centrioles.

Detailed explanation-2: -Metaphase: During metaphase, each of the 46 chromosomes line up along the center of the cell at the metaphase plate.

Detailed explanation-3: -During metaphase I, the homologous chromosomes are arranged in the center of the cell with the kinetochores facing opposite poles. The homologous pairs orient themselves randomly at the equator.

Detailed explanation-4: -Answer and Explanation: The above statement, “Homologous pairs of chromosomes line up at the metaphase plate during metaphase II” is a true statement.
