Prophase 1

DNA coils into chromosomes, the nucleolus and nuclear envelope disappear, the mitotic spindle forms, and synapsis (crossing-over) occurs.

Metaphase 1

Tetrads line up randomly along the midline, spindle fibers attach to the centromere of each homologous chromosome.

Anaphase 1

Homologous chromosomes move to the opposite poles of the cell

Telophase 1

The chromosomes reach the opposite end of cell and cytokinesis begins

Prophase 2

Spindle fibers form and begin to move the chromosomes toward the midline of the dividing cell.

Metaphase 2

Chromosomes move to the midline of the dividing cell, facing opposite poles of the dividing cell

Anaphase 2

The chromatids seperate and move toward opposite poles of the cell.

Telophase 2

A nuclear membrane forms around the chromosomes in each of the 4 new cells.
