1
prophase
chromosomes double and thicken nuclear membrane disappears
2
metaphase
homologous pairs of chromosomes line up at center of cell. Spindle fibers attach
3
anaphase
Homologous pairs separate and move to opposite sides of cell
4
telophase
nuclear membrane reforms
5
prophase 2
two cells are formed. Each contains one doubled chromosome from each homologous pair. Chromosomes do not double again.
6
metaphase 2
Chromosomes line up along the center of the cell
7
anaphase 2
Doubled chromosomes split at the center and are pulled to opposite sides of the cell
8
telophase 2
four cells are formed
