   • The spindle fibers attach to the centromeres of the chromosomes in metaphase.
   • Metaphase is a critical checkpoint for proper chromosome segregation.

2. Second stage of meiosisC1formalscientific

   The stage of cell division in meiosis where homologous chromosomes (in meiosis I) or sister chromatids (in meiosis II) align at the cell's equator.

   Segunda fase da meiose

   • In meiosis I, metaphase I aligns homologous chromosome pairs.
   • Metaphase II in meiosis is similar to mitotic metaphase.
   • Errors in metaphase alignment can lead to genetic disorders.
