Meiosis is the process by which one parent cell (with a full set of chromatids) divides to form 4 daughter cells or gametes. Meiosis is a one way process, it is not a cycle.
meiosis 1 is the first half of meiosis. it results in 2 haploid daughter cells. |
Meiosis 1
|
|
Chromosomes form and each one pairs with its sister chromosome forming a tetroid. In a process called crossing over parts of their chromatids are switched so all daughter cells will be differnent.
|
Prophase 1
|
|
Crossing Over
-parts of the chromosomes breaking off and then reattching to the opposite chromosome. |
Metaphase 1
|
|
Homolugus chromosomes are split and move to opposite sides of the cell.
|
Anaphase 1
|
|
A nucleur envelope forms and cytokenesis separates the two cells. Each daughter cell is genetically different from the parent cell.
|
Telophase 1
|
|
meiosis 2 is the second half of Meiosis. It results in 4 haploid gametes or cells.
|
Meoisis 2
|
|
The nucleur envelope disappears as the nucleus of each haploid cell prepares to divide.
|
Prophase 2
|
|
Chromosomes line up in the middle of the cell.
|
Metaphase 2
|
|
sister chromtids are pulled apart and move to opposite sides of the cell.
|
Anaphase 2
|
|
A nucleur envelope forms and cytokinesis separates the cells into 4 genetically different haploid gametes.
|
Telophase 2
