Now what happens in meiosis? What happens in meiosis? I'll do that over here.
Things go through mitosis, they can then go through the entire cell cycle again. Single cell organism into you, or for the most part, into you. And this is actually how most of the cells in your body grow. It grows and it can replicate its DNA and centrosomes and grow some more then each of these can And now each of these cells are just like this cell was, it can go through interphase again. So you now have two cells that each have the diploid Now after the process of mitosis happens and you have yourĬytokinesis and all the rest, you end up with two cells that each have the same genetic 46 for humans, you get 23Ĭhromosomes from your mother, 23 chromosomes from yourįather or you can say you have 23 homologous pairs, So, in mitosis, this is all a review, if you've watched the mitosis video, in mitosis, we start with a cell, that has a diploid number of chromosomes. Go in-depth on meiosis, I want to do a very high level overview comparing mitosis to meiosis. ‡Note: For information on other modes of sexual reproduction: §Note: Other forms of asexual reproduction include budding and binary fission (the most common type of cell division in prokaryotes). †Note: Not all sources make this distinction. This whole process is sexual reproduction, so it would be true to say that meiosis is a part of sexual reproduction.
These cells typically become gametes in animals (other forms of life are more complicated‡) that then fuse to form zygotes that represent the next generation for that species. (Genetic recombination also takes place during meiosis.) In contrast, meiosis is a method for producing new cells with half the number of chromosomes that were found in the mother cell. Thus, mitosis is one way§ that asexual reproduction can occur, but only when the cell is an entire organism. yeasts) mitosis does result in asexual reproduction, but this not usually true in multicellular eukaryotes.
Mitosis is the eukaryotic method for producing new cells with the same genetic composition as the mother cell.įor single celled eukaryotic organisms (e.g. Mitosis and meiosis are about the production of new cells. Not quite - reproduction is usually† used to mean the production of new organisms.
