1.

MEIOSIS

MEGANNE DERMONT, CHELSEA LUCAS, NICK SMITH
2.

Interphase
Cells go through a round of DNA replication, making duplicate chromosomes.

3.

Prophase 1
Each chromosome pairs with its corresponding homologous. The nuclear envelope starts to disappear.

4.

Metaphase 1
Spindle fibers attatch to the chromosomes

5.

Anaphase 1
The fibers pull the homologous chromosomes toward opposite ends of the cell.

6.

Telophase 1
The nuclear membrane reforms around the chromosomes.

7.

Cytokinesis 1
The cell separates into two cells.

8.

MEIOSIS 2

(NO INTERPHASE 2)
9.

Prophase 2
Meiosis results in two haploid daughter cells, each with half the numbers of chromosomes

10.

Metaphase 2
The chromosomes line up in a similar way to the metaphase stage of meiosis.

11.

Anaphase 2
The sister chromatids separate and move towards opposite ends of the cell.

12.

Telophase 2 and Cytokinesis 2
These phases end in four haploid cells.
