prophase

chromosomes double and thicken nuclear membrane disappears

metaphase

homologous pairs of chromosomes line up at center of cell. Spindle fibers attach

anaphase

Homologous pairs separate and move to opposite sides of cell

telophase

nuclear membrane reforms

prophase 2

two cells are formed. Each contains one doubled chromosome from each homologous pair. Chromosomes do not double again.

metaphase 2

Chromosomes line up along the center of the cell

anaphase 2

Doubled chromosomes split at the center and are pulled to opposite sides of the cell

telophase 2

four cells are formed
