Differences between Mitosis and Meiosis

Meiosis

Definition: part of the process of gamete formation, consisting of chromosome conjugation and two cell divisions, in the course of which the diploid chromosome number becomes reduced to the haploid.

Occurs during gamete formation. (sex organs)

4 daughter cells are formed.

Cells are not identical to parent cells.

Homologous chromosomes cross over.

2 visions are required to complete this process.

Centromeres divide in anaphase II but not anaphase I

Mitosis

Definition: a type of cell division that results in two daughter cells each having the same number and kind of chromosomes as the parent nucleus, typical of ordinary tissue growth.

The process of when a eukaryotic cell separates into 2 sets of chromosomes of equal and identical nuclei with equal distribution of organelles.


Phases:

Prophase

Metaphase

Anaphase

Telophase


Occurs for growth/repair of cells.

2 daughter cells are formed.

Crossing Over does not occur.

1 division completes this process.

Centimeters divide in anaphase.
