Gennadij [26K]
<h3><u>Answer;</u></h3>

In metaphase I, the chromosome tetrads align on metaphase plate while in metaphase II, chromosomes align on metaphase plate as they are in mitosis with only sister chromatids.

<h3><u>Explanation;</u></h3>
  • Meiosis is a form of cell division that halves number of chromosomes when forming specialized reproductive cells such as gametes .
  • Meiosis occurs in two phases, namely; meiosis I and meiosis II. During homologous pairs of chromosomes align on the equatorial plane at the center of the cell.
  • During metaphase II, the spindle fibers connect to the kinetochore of each sister chromatid. The chromosomes align at the equatorial plane, which is rotated 90° compared to the equatorial plane in meiosis I.
