Mention the differences between mitosis and meiosis?

Sure, here are the main differences between mitosis and meiosis:

1. Purpose: Mitosis is a process of asexual reproduction in which the cell divides in two producing a replica, with an equal number of chromosomes in haploid cell. Meiosis is 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.

2. Number of Divisions: Mitosis undergoes one round of cell division that results in two daughter cells, while meiosis undergoes two rounds of cell division that results in four daughter cells.

3. Number of Daughter Cells and Genetic Composition: Mitosis produces two genetically identical daughter cells with the same number of chromosomes as the parent cell. Meiosis, on the other hand, produces four genetically different daughter cells with half the number of chromosomes of the parent cell.

4. Role in the Body: Mitosis is responsible for the growth and repair of cells in the body. Meiosis, however, is responsible for the production of gametes (sex cells) for sexual reproduction.

5. Crossing Over: In mitosis, there is no crossing over of chromosomes, meaning the genetic material is copied exactly. In meiosis, crossing over can occur during the first division, leading to genetic variation in the daughter cells.

6. Type of Reproduction: Mitosis is involved in asexual reproduction, while meiosis is involved in sexual reproduction.

7. Pairing of Homologues: In mitosis, homologous chromosomes never pair up, while in meiosis, homologous chromosomes pair up during the first division.

8. DNA Replication: In mitosis, DNA replication occurs during the S phase of the cell cycle. In meiosis, DNA replication also occurs only once, but it is followed by two rounds of cell division.
