What are the differences and Similarities of Them?
Mitosis and Meiosis
Mitosis and Meiosis are cell Division.
There are two types of cell division: mitosis and meiosis. Most of the time when people refer to “cell division,” they mean mitosis, the process of making new body cells.
Meiosis and Mitosis
What are they?
Meiosis is the process in eukaryotic, sexually-reproducing animals that reduces the number of chromosomes in a cell before reproduction.
Mitosis is the process in which a eukaryotic cell nucleus splits in two, followed by division of the parent cell into two daughter cells. The word "mitosis" means "threads," and it refers to the threadlike appearance of chromosomes as the cell prepares to divide.
Similarities and Differences
Mitosis and meiosis are both processes which describe the production of new cells. Mitosis produces 2 daughter cells which are genetically identical to the parent cell. Each daughter cell is diploid (contains the normal number of chromosomes). This is the result of DNA replication and 1 cell division. Mitosis is used in growth and asexual reproduction. Meiosis produces 4 daughter cells, each of which are unidentical to the parent cell and to one another. Each daughter cell is haploid (contains half the number of normal chromosomes). This is the result of DNA replication, followed by crossing over of homologous chromosomes and separation of chromosomes. There are two cell divisions: the parent cell divides once and then each cell produced by this first division divides once. Meiosis is used to produce gametes (sperm and egg cells), the cells of sexual reproduction. Two gametes fuse to form a zygote, a diploid cell with the full number of chromosomes.
