Metaphase:

- The chromosomes connected to spindle
fibers are arranged along the cell equator.

Anaphase:

- The centromere of the chromosomes
split lengthwise into two halves,
so the chromatids separate from each other.

- Spindle fibers begin to shrink and two identical
groups of chromosomes.

- are formed each group of chromosomes
migrate to one of the cell's poles

Telophase:

- The spindle fibers disappear.
- A nuclear membrane is formed at each pole
of the cell to form two nuclei one at each
pole.
- At the end of this phase the cell divides into
two new cells each one
contains (2N) chromosomes.
