WebShort Notes on Metaphase. Metaphase is the second step of mitotic cell division after prophase. Metaphase is characterised by the alignment of the duplicated chromosomes … WebMetaphase I: In metaphase I of meiosis, the tetrads align on the equatorial plate (as in mitosis). The centromeres attach to spindle fibers, which extend from the poles of the cell. One centromere attaches per spindle fiber. Anaphase I: In anaphase I, the homologous chromosomes or tetrads separate.
