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.

Mitosis and meiosis are both types of cell division. Though there are similarities between mitosis and meiosis, there are some key differences between these two processes. Mitosis is how new body cells are produced, whereas meiosis is used to produce gametes (i.e. sperm and egg cells).
Mitosis is how the cells of your body reproduce. During mitosis, a diploid parent cell (i.e. a cell with two sets of chromosomes) makes a complete copy of its DNA before splitting in two. This process produces two genetically identical daughter cells and takes place across five phases. The phases of mitosis are prophase, prometaphase, metaphase, an...
Almost all of your body’s cells divide by mitosis. Meiosis is used to produce only one type of cell, and those are the gametes. During meiosis, a diploid cell divides to produce four, non-identical haploid daughter cells, each containing a single set of chromosomes. In humans, these are sperm and egg cells. Unlike mitosis, meiosis involves two roun...
Meiosis I
Like mitosis, meiosis I takes place across five stages. Before this first round of cell division begins, the cell’s DNA is replicated during the interphase of the cell cycle.
Meiosis II
Meiosis II is very similar to the process of mitosis, except it involves two haploid cells rather than one diploid cell.

Before meiosis I starts, the cell goes through interphase. Just like in mitosis, the parent cell uses this time to prepare for cell division by gathering nutrients and energy and making a copy of its DNA. During the next stages of meiosis, this DNA will be switched around during genetic recombination and then divided between four haploid cells.

Dec 8, 2016 · Meiosis is the process in eukaryotic, sexually-reproducing animals that reduces the number of chromosomes in a cell before reproduction. Many organisms package these cells into gametes, such as egg and sperm. The gametes can then meet, during reproduction, and fuse to create a new zygote. Because the number of alleles was reduced during meiosis ...
S is the period of DNA synthesis, where cells replicate their chromosomes. G2 is the period between the end of DNA replication and the start of cell division. Cells check to make sure DNA replication has successfully completed, and make any necessary repairs. M is the actual period of cell division, consisting of prophase, metaphase, anaphase ...
Aug 8, 2023 · The two broad phases of the cell cycle are interphase and mitosis. During interphase, cells grow, replicate their DNA and organelles, and prepare for division. Interphase steps are the first gap phase (G 1), the synthesis phase (S), and the second gap phase (G 2). Cells divide during mitosis (M). The final step of mitosis, or the following step ...

May 11, 2006 · Here are all the stages of mitosis—from the first step, interphase, to the last, cytokinesis. enters mitosis, it undergoes a period of growth called interphase. About 90% of a cell's time in the normal. In this phase, the cell increases in mass in preparation for cell division. The G1 phase is the first gap phase.
