Meiosis: Metaphase I

Metaphase I starts when the tetrads are at the center of the cell (Fig. 9). The tetrads line up along the center of the cell during metaphase I of meiosis.  The tetrads have stayed together which ensures that during the first division, each cell will get one chromosome from each homologous pair. The chromosomes remain at the center of the cell until the homologous pairs are ready to move away from each other.
