MITOSIS
|
MEIOSIS
|
|
1. It is a process of Asexual reproduction.
|
1 It is a process of sexual reproduction
|
|
2. It occurs in Vegetative or Somatic cells. (Any cell of a living organism other than the reproductive
cells.) Ex.: All living organisms other than reproductive cells
|
2 It occurs in Reproductive or Germ
cells. ( Cell that
gives rise to the gametes of an organism that reproduces sexually.) Ex.:
Reproductive cells of Humans, Animals, Plants and Fungi
|
|
3. It creates or makes everything
other than sex cells.
|
3. It creates or makes sex cells only.
Female egg cells or male sperm cells.
|
|
4. Nucleus divides only Once.
|
4. Nucleus divides Twice.
|
|
5. Two daughter cells are formed.
|
5. Four daughter cells are formed.
|
|
6. Daughter cells are diploid. ( A
cell or nucleus containing two complete sets of chromosomes, one from each
parent.)
|
6. Daughter cells are haploid. ( A cell or nucleus having a single set of
unpaired chromosomes.)
|
|
7. Daughter cells forms somatic organs.
|
7. Daughter cells forms gametes.
|
|
8. It occurs more frequently.
|
8. It occurs less frequently.
|
|
9. Genetically produces identical organisms or
cells.
|
9. Genetically different cells or organisms
produces.
|
|
10. Chromosomes remain the same.
|
10. Chromosomes reduced by half.
|
|
11.
Steps of mitosis are
Interphase, Prophase,
Metaphase, Anaphase, Telophase
and Cytokinesis
|
11. Steps of Meiosis are Interphase,
Prophase-I, Metaphase-I,
Anaphase-I, Telophase-I, Prophase-II, Metaphase- II, Anaphase-II , and Telophase-II.
|
|
12. Mitosis discovered by Walther
Flemming.
|
12. Meiosis
discovered by Oscar Hetwig.
|
|
13. No
crossing over in chromosomes. (Chromosome Crossing over cannot occurs)
|
13. Crossing over occurs in Chromosomes (Mixing of
chromosomes can occurs.)
|
|
14. Equation division.
|
14. Reduction division.
|
|
15. Chromosome number doubles at the
beginning of each cell division.
|
15. Chromosome number is not doubled.
It doubles after the end of first meiotic division.
|
|
16. Karyokinesis – Occurs in Interphase.
|
16. Karyokinesis – Occurs in Interphase I
|
|
17. Cytokinesis – Occurs in Telophase
|
17. Cytokinesis – Occurs in Telophase I and Telphase II
|
|
18. The centromere splits during Anaphase
|
18. The centromeres do not separate during
Anaphase I but during Anaphase II
|
|
19. Mother Cell contains (2n) and
Daughter Cell contains (2n)
|
19. Mother Cell contains (2n) and
Daughter Cell contains (n)
|
|
20. Mitosis Definition : A process of Asexual
reproduction in which the cell divides into two, producing a replica with an
equal number of chromosomes in each resulting diploid cell.
|
20. Meiosis Definition: A type of cellular reproduction in
which the number of chromosomes are reducing by half producing two haploid
cells.
