Mitosis & Meiosis

MITOSIS
The Phases of Mitosis
Metaphase; the second phase of mitosis. During this phase the chromosomes line up down the center of the cell. Every chromosome connects to a spindle fiber.
Anaphase; the third phase of mitosis. During anaphase, chromosome seperate from each other until they are in two completely different groups at each end of the cell. This phase usually ends when the chromosomes stop moving.
Telophase; the fourth phase of mitosis. During this last phase, while the chromosomes are at opposite ends of the cell from going through anaphase, two new nuclear envelopes start to form.

Crossing Over
Crossing over benefits genetics and is very important because it creates a variation of possible allele combinations in gametes, therefor creating a wide variety of genetic diversity.
To Summarize...
Mitosis is to help body cells grow and develop, whereas meiosis is to produce sex cells.
Mitosis results in two identical diploid daughter cells, whereas meiosis begins with a diploid cell but results in four completely different haploid cells.
