Jan 22, 2021 · Mitosis and meiosis are both types of cell division. Mitosis is the process by which most cells in the body divide, involves a single round of cell division, and produces two identical, diploid daughter cells. Meiosis is the process by which gametes are produced. Meiosis involves two rounds of cell division and produces four non-identical ...

Sep 12, 2023 · Outcome. While mitosis yields two daughter cells that are genetically identical (2n) to the parent cell, meiosis produces four haploid (n) cells that are genetically different from the parent cell. Mitosis: Two identical daughter cells. Meiosis: Four non-identical daughter cells with half the chromosome number.

- Cell Division. Mitosis: A somatic cell divides once. Cytokinesis (the division of the cytoplasm) occurs at the end of telophase. Meiosis: A reproductive cell divides twice.
- Daughter Cell Number. Mitosis: Two daughter cells are produced. Each cell is diploid containing the same number of chromosomes. Meiosis: Four daughter cells are produced.
- Genetic Composition. Mitosis: The resulting daughter cells in mitosis are genetic clones (they are genetically identical). No recombination or crossing over occur.
- Length of Prophase. Mitosis: During the first mitotic stage, known as prophase, chromatin condenses into discrete chromosomes, the nuclear envelope breaks down, and spindle fibers form at opposite poles of the cell.
- End Result. Produces two daughter cells. Produces four daughter cells.
- Chromosome Number. The daughter cells are diploid (2n). The daughter cells are haploid (n).
- Genetic Composition. Daughter cells are genetically identical. Daughter cells are genetically different.
- Main Purpose. a) Growth, repair, and replacement of old, damaged cells in higher organisms; a form of asexual reproduction in lower organisms (prokaryotes).
Most of these differences relate back to the fact that, although both are needed for cell replication, mitosis and meiosis have different purposes: mitosis replaces body cells with identical copies, while meiosis creates genetically different sex cells that will be used to create an entirely new organism. Another difference between mitosis and ...
Table 3.6.1 Differences between Mitosis and Meiosis in Humans (Diploid #46) Cell Processes. Mitosis. Meiosis. Creates. all the cells in your body except sex cells. sex cells only; Female egg cells or Male sperm cells. Definition. process of cell division that forms two new cells (daughter cells), each of which has the same number of chromosomes.

Meiosis is a more specific type of cell division (of germ cells, in particular) that results in gametes, either eggs or sperm, that contain half of the chromosomes found in a parent cell. Unlike mitosis with its many functions, meiosis has a narrow but significant purpose: assisting sexual reproduction. It is the process that enables children ...
