What Is Meiosis? How Are Mitosis and Meiosis Similar? From left to right: interphase, prophase, metaphase, anaphase, telophase, cytokinesis What Is the Difference Between Mitosis and Meiosis? During anaphase II, sister chromatids are separated to opposite ends of the cell Number of cells created End result: two daughter cells End result: four daughter cells Ploidy Creates diploid daughter cells Creates haploid daughter cells Genetics Daughter cells are genetically identical Daughter cells are genetically different.
Christine Sarikas. About the Author. Search the Blog Search. Ends with cytokinesis. Meiosis Diploid parent cell Consists of interphase, prophase, metaphase, anaphase and telophase but twice! In metaphase II individual chromosomes pairs of chromatids line up along the equator. Related Content:. What is mitosis? What is meiosis? What is a cell?
What is a stem cell? I'll just write 2n to show it has a diploid number. For human beings, this would be 46 chromosomes. Now after the process of mitosis happens and you have your cytokinesis and all the rest, you end up with two cells that each have the same genetic information as the original. So you now have two cells that each have the diploid number of chromosomes. So, 2n and 2n. And now each of these cells are just like this cell was, it can go through interphase again.
It grows and it can replicate its DNA and centrosomes and grow some more then each of these can go through mitosis again. And this is actually how most of the cells in your body grow.
This is how you turn from a single cell organism into you, or for the most part, into you. So that is mitosis. It's a cycle. After each of these things go through mitosis, they can then go through the entire cell cycle again. Let me write this a little bit neater.
Mitosis, that s was a little bit hard to read. Now what happens in meiosis? What happens in meiosis? I'll do that over here. In mitosis, the daughter cells have the same number of chromosomes as the parent cell, while in meiosis, the daughter cells have half the number of chromosomes as the parent.
The daughter cells produced by mitosis are identical, whereas the daughter cells produced by meiosis are different because crossing over has occurred. The events that occur in meiosis but not mitosis include homologous chromosomes pairing up, crossing over, and lining up along the metaphase plate in tetrads. Meiosis II and mitosis are not reduction division like meiosis I because the number of chromosomes remains the same; therefore, meiosis II is referred to as equatorial division.
When the homologous chromosomes separate and move to opposite poles during meiosis I, the ploidy level is reduced from two to one, which is referred to as a reduction division. Key Terms reduction division : the first of the two divisions of meiosis, a type of cell division ploidy : the number of homologous sets of chromosomes in a cell equatorial division : a process of nuclear division in which each chromosome divides equally such that the number of chromosomes remains the same from parent to daughter cells.
Comparing Meiosis and Mitosis Mitosis and meiosis are both forms of division of the nucleus in eukaryotic cells. Authored by : Boundless. Provided by : Boundless.
