Meiosis Overview  Meiosis is the uniting of male and female gametes through sexual reproduction. Each gamete begins with pairs of 23 chromosomes and after combination each has 46.

Interphase  Interphase is the stage of a cell in which a cell spends most of its life. During this stage the cell performs most of its main function and prepares for cell division.

Prophase I  In this stage of meiosis the chromosomes come together in pairs.

Metaphase I  During this stage of meiosis the pairs of chromosomes, or bivalents, line up along the equator of the cell.

Anaphase I  During anaphase the pairs separate and move to the poles of the cells.

Telophase I At this stage the cell divides creating two daughter cells.

Prophase II  During prophase II the daughter cells again replicate to create pairs.

Metaphase II  During metaphase II the bivalents in the daughter cells line up along the equator of their respective cells.

Anaphase II  At this stage the bivalents in each daughter cell separate and move to the poles of their cells.

Telophase II  At this point the two daughter cells split apart. This leaves four complete daughter cells with a complete set of chromosomes.

Cytokinesis It is division of the cytoplasm of a cell following the division of the nucleus. So, at the end of meiosis there are four new daughter cells.
