In humans, tissues such as the skin and blood contain cells that are actively dividing, whilst other tissues such as fat contain cells that expand (good if you need energy for winter, bad if you are trying to fit into some expensive jeans). Other cells, such as neurons, will never divide again once they are terminally differentiated; they are post-mitotic. In the process of replicating themselves, cells have another choice: do they want to make an identical copy and be left with two cells? Or do they want to make four “half-copies”, in preparation for sexual reproduction, where their genetic content will be made whole again by the process of fertilization? This choice is the choice between mitosis and meiosis. There are two types of cell division: mitosis and meiosis. Mitosis is the process by which body cells divide and create copies of themselves for growth and repair. In meiosis, the new cells have half the genetic material of the parent cell and is the process by which egg and sperm cells are ...

At the start, all the cells are 2n, diploid cells. By far the largest difference between meiosis I and mitosis is that mitosis results in genetically identical, diploid somatic cells. Meiosis, in it's entirety, results in gametes of haploid genetic information, but the genetic information is not identical due to crossing-over events that happened during meiosis I. What you should also note from the figure: Each chromatid represents 1 DNA molecule. In mitosis, the cell will begin with 4 chromosomes and 8 chromatids. After cytokinesis, the somatic cell will have 4 chromatids and 4 chromosomes. This propagates during the next round of mitosis. In meiosis: The cell starts with 8 chromatids and 4 chromosomes. After meiosis I each cell has 4 chromatids and 2 chromosomes. After meiosis II, each cell has 2 chromatids and 2 chromosomes. You're halving the amount of genetic material each round of meiosis, and this can't be propagated indefinitely. Source: Tortora, GJ (2008). Principles of Anatomy and Physiology. 12th ED.

Mitosis and Meiosis: What's the Difference? Posted on 7/11/22 by Laura Snider Did you know that right now, inside your body, some of your cells are making copies of themselves? Don’t worry—that’s normal. Your cells need to make copies of themselves so that they can replace old, dead cells. It’s the circle of life, Simba. Somatic cells—that is, the cells in your body that aren’t sex cells—do this via a process called mitosis. New sex cells, or gametes, are produced via a different process, called meiosis. Today, we’re going to talk about both of these. How are they different? How are they similar? Keep reading and you’ll find out! The Cell Cycle and Mitosis: You Are Your Own Clone Army Just like us multicellular organisms, cells have a cycle of life. The cell cycle. Image from Most of a cell’s time is spent in Interphase, the largest section of the pie-chart-looking graphic above. But there comes a time in most cells’ lives when they’ve got to reproduce. In the S phase, the cell prepares for this by creating copies of all its DNA. (You can read more about replication 2, the cell continues growing and preparing for mitosis. We’ll save G 1 for later. There are four phases of mitosis: prophase, metaphase, anaphase, and telophase. I’m sure there are lots of mnemonic devices out there for memorizing them, but the one my seventh-grade science teacher taught me is the one I’ve remembered to this day: "Paul Meets Anne Tonight." Feel free to use something more exciting, like “Poison...

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 haploid daughter cells. Cell division What are Mitosis and Meiosis? 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 vs. Meiosis Mitosis Meiosis One cell division Two cell divisions Produces two daughter cells Produces four daughter cells Produces diploid cells Produces haploid cells Daughter cells are genetically identical Daughter cells are non-identical Produces body cells Produces sex cells No crossing-over occurs Crossing-over occurs Homologous chromosomes do not pair up Homologous chromosomes do not pair up Mitosis 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, anaphase, and telophase. Before mit...

Difference Between Mitosis And Meiosis From an academic perspective, understanding the difference between mitosis and meiosis is crucial. Read on to explore what is mitosis and meiosis, significant similarities and differences between the two: Meiosis Meiosis is a type of cell division that results in the formation of four daughter cells each with half the number of chromosomes as the parent cell. Mitosis Mitosis is the type of cell division that results in the formation of two daughter cells each with the same number and kind of chromosomes as the parent cell. Table of Contents • • • • • • Introduction In single-celled organisms, cell reproduction gives rise to the next generation. In multicellular organisms, cell division occurs not just to produce a whole new organism but for growth and replacement of worn-out cells within the organisms. 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.
