Meiosis

Mitosis

Definition: 

A type of cellular reproduction in which the number of chromosomes is reduced by half through the separation of homologous chromosomes in a diploid cell.

A process of asexual reproduction in which the cell divides into two producing a replica with an equal number of chromosomes in a haploid cell. 

Several daughter cells produced:

4

2

Creates:

Sex cells only: Female egg cells or male sperm cells makes makes makes

Makes everything other than sex cells

Occurs in 

Humans, Animals, Plants, and fungi

All organisms produces 

Produces: 

Four haploid Daughter cells to

Two diploid daughter cells

Steps:

The steps of Meiosis are interphase, Prophase I, Metaphase I, Anaphase I, Telophase I, Prophase II, Metaphase II, Anaphase II, and Telophase II

The steps of Mitosis are interphase, Prophase, Metaphase, Anaphase, Telophases,e, and Cytokinesis.

Identical

Cytokinesis:

Occurs in telophase I and Telophase II

Occurs in telophase

Function: 

Sexual Reproduction

Cellular reproduction & general growth and repair of the body chromosome chromosome

Chromosome number: 

Reduced by half remains remains

Remains the same

Karyokinesis: 

Occurs in interphase I

Occurs in interphase

Crossing Over:

Mixing of chromosomes

Do not occur

Centromeres split: 

The centromeres do not separate during Anaphase I but during anaphase II.

The centromeres split during anaphase

Occurrence of crossing over 

Yes

No
