Differentiate between meiosis or mitosis
Answers
BASIS FOR COMPARISON MITOSIS MEIOSIS
Meaning : Mitosis is the process of cell division which occurs in all types of cells (excluding sex cells), with the purpose of the asexual reproduction or the vegetative growth.
Meaning : Meiosis is the process occurs in the specialized type of cell called as meiocytes, which supports the sexual reproduction by the gametogenesis.
Discovered by Walther Flemming. Oscar Hertwig.
Steps required to complete the cycle Prophase, Metaphase, Anaphase, Telophase.
Prophase I, Metaphase I, Anaphase I, Telophase I; (Meiosis II), Prophase II, Metaphase II, Anaphase II and Telophase II.
Occurs in Somatic cells. Germ cells.
Other Features There is no process of synapsis and crossing over. Synapsis and crossing over take place of the Homologous chromosomes during meiosis I.
The genetic identity remains same even after the mitotic division. Genetic variation is noticed during meitoic divison.
There is only one nuclear division. There are two nuclear divisions.
There is no pairing of Homologs. Pairing occurs of Homologs.
Mother cell can be diploid or haploid. Mother cell is always diploid.
There is the production of two daughter cells, which are diploid. There is the production of four haploid daughter cells.
The number of chromosomes remains same. The chromosome number is reduced by half.
