Mitosis/Meiosis Comparison

Big image

Difference 1: Type of Reproduction

Mitosis: Asexual

Meiosis: Sexual

Difference 2: Occurs in

Mitosis: All organisms.

Meiosis: Humans, animals, plants, fungi.

Difference 3: Genetically

Mitosis: Identical

Meiosis: Different

Difference 4: Crossing Over

Mitosis: No, crossing over cannot occur.

Meiosis: Yes, mixing of chromosomes can occur.

Difference 5: Definition

Mitosis: A process of asexual reproduction in which the cell divides in two producing a replica, with an equal number of chromosomes in each resulting diploid cell.

Meiosis: A type of cellular reproduction in which the number of chromosomes are reduced by half through the separation of homologous chromosomes, producing two haploid cells.

Difference 6: Pairing of Homologs

Mitosis: No

Meiosis: Yes

Difference 7: Function

Mitosis: Cellular reproduction and general growth and repair of the body.

Meiosis: Genetic diversity through sexual reproduction.

Difference 8: Number of Divisions

Mitosis: 1

Meiosis: 2

Difference 9: Number of Daughter Cells produced

Mitosis: 2 diploid cells

Meiosis: 4 haploid cells

Difference 10: Chromosome Number

Mitosis: Remains the same.

Meiosis: Reduced by half.

Difference 11: Steps

Mitosis: Prophase, Metaphase, Anaphase, Telophase.

Meiosis: (Meiosis 1) Prophase I, Metaphase I, Anaphase I, Telophase I

(Meiosis 2) Prophase II, Metaphase II, Anaphase II and Telophase II.

Difference 12: Karyokinesis

Mitosis: Occurs in Interphase.

Meiosis: Occurs in Interphase I.

Difference 13: Cytokinesis

Mitosis: Occurs in Telophase.

Meiosis: Occurs in Telophase I and in Telophase II.

Difference 14: Creates

Mitosis: Makes everything other than sex cells.

Meiosis: Sex cells only: female egg cells or male sperm cells.

Difference 15: Discovered by

Mitosis: Walther Flemming

Meiosis: Oscar Hertwig
