|
|
Mitosis produces cells that identical to the parent cell.
|
|
|
Meiosis produces cells that have half the number of chromosomes as the parent cell.
|
|
|
All cells go through INTERPHASE as part of the cell cycle, whether it goes to mitosis or meiosis next.
|
|
|
In both types of cell division, the chromosomes are only duplicated once.
|
|
|
Only in Mitosis, do you see chromosomes pair up to form a tetrad.

Detailed explanation-1: -1 Answer. Mitosis gives two nuclei, and hence two cells, while meiosis gives four. Mitosis gives identical cells to each other and to the mother cell, while meiosis leads to genetic variation due to crossing over and independent assortment.
Detailed explanation-2: -Mitosis results in two nuclei that are identical to the original nucleus. Meiosis, on the other hand, results in four nuclei, each having half the number of chromosomes of the original cell. In animals, meiosis only occurs in the cells that give rise to the sex cells (gametes), i.e., the egg and the sperm.
Detailed explanation-3: -Mitosis consists of one stage whereas meiosis consists of two stages. Mitosis produces diploid cells (46 chromosomes) whereas meiosis produces haploid cells (23 chromosomes). Mitosis produces two identical daughter cells whereas meiosis produces four genetically different daughter cells.
Detailed explanation-4: -The cleavage of the centromere is taken place in Anaphase of Mitosis, whereas it does not occur in Anaphase I of meiosis.
