Mitosis vs. Meiosis

By: Daniel Byrd

Difference In Reproduction

- Mitosis goes through Asexual Reproduction, which is the reproduction of an organism from a single parent cell.

- Meiosis goes through Sexual Reproduction, which is when 1 female egg cell combines with 1 male sperm cell.

Difference In Number of Daughter Cells Produced

- In Mitosis, 2 diploid cells are produced because during PMAT a cell is multiplied, and then divided to get 2 diploid cells with the exact number of chromosomes.

- In Meiosis, 4 haploid cells are produced because during Meiosis the cell is multiplied, then it's divided once in Meiosis 1, and then it's divided again in Meiosis 2 to get 4 haploid cells.

Difference In Number of Divisions

- In Mitosis there is only 1 division, Prophase, Metaphase, Anaphase, Telophase, because Mitosis only creating 2 new cells with the same number of chromosomes.

- In Meiosis there is 2 divisions (Meiosis I, and Meiosis II) in Meiosis I a cell is multiplied and then divided to get 2 new cells, and in Meiosis II the 2 new cells are divided again to get 4 haploid cells.

Difference In Genes

- In Mitosis the genes inside every chromosome are genetically identical because the chromosomes in Mitosis goes through Asexual Reproduction.

- In Meiosis the genes inside every chromosome are genetically different because the chromosome in Meiosis goes through Sexual Reproduction.

Difference In the Number of Chromosomes

- In Mitosis the number of chromosomes stays the same because all you are doing is creating 2 new cells with the exact number of chromosomes.

- In Meiosis the number of chromosomes is 1/2 the number of the original cell because you in Meiosis I the cell is multiplied, and divided, and in Meiosis II is it divided again.

Difference In Cross Over

- In Mitosis cross over can't occur because there is no sister chromatids that can align in the middle.

In Meiosis cross over can occur because homologous chromosomes pair up and exchange genetic material

Difference In what Mitosis and Meiosis Occurs In

- Mitosis occurs in all organisms because it is in charge of growth and repair.

- Meiosis only occurs in humans, animals, plants, and fungi, because it is in charge of producing sex cells for reproduction.
