Meiosis vs Mitosis
Cell division and reproduction can occur in two ways - mitosis and meiosis.
Mitosis is a process of cell duplication, or reproduction, during which one cell gives rise to two
genetically identical daughter cells.
Meiosis, on the other hand, is a division of a germ cell involving two fissions of the nucleus and
giving rise to four gametes, or sex cells, each possessing half the number of chromosomes of the
Mitosis is used by single celled organisms to reproduce; it is also used for the organic growth of
tissues, fibers, and mibranes. Meiosis is useful for sexual reproduction of organisms; The male
and female sex cells, e.g. the spermazoa and egg, fuse to create a new, singular biological
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.
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.
Function: sexual reproduction
Cellular Reproduction & general
growth and repair of the body
Occurs in: Humans, animals, plants, fungi all organisms
Genetically: different identical
Yes, mixing of chromosomes can
No, crossing over cannot occur.

Reduced by half Remains the same
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,
Telophase and Cytokinesis
Karyokenesis: Occurs in Interphase I Occurs in Interphase
Cytokenesis: Occurs in Telophase I & Telohpase II Occurs in Telophase
The centromeres do not separate during
anaphase I, but during anaphase II
The centromeres split during
Sex cells only: Female egg cells or
Male sperm cells
Makes everything other than sex
