Meiosis


Meiosis is a type of cell division that happens during sexual reproduction and results in four unique daughter cells that each have half the number of the parental cell’s chromosomes (as opposed to mitosis which results in two daughter cells that are identical to the parental cell.

You can find a mitosis specific post by scrolling down in our feed. These differences occur because meiosis, unlike mitosis, has two rounds of cell division (meiosis I and meiosis II), resulting in the halving of the number of chromosomes in the daughter cells. Both rounds of cell division follow the prophase, metaphase, anaphase, telophase, cytokinesis steps that can be found in mitosis, with some slight differences.

Meiosis also differs from mitosis in the way that it involves recombination, during which homologous chromosomes that have been paired up (in a process called synapsis) exchange segments, “mixing up” the genetic information. This creates variations in the genetic code and results in almost unlimited combinations, which leads to each daughter cell being completely unique. Oh, and let's throw in a fun fact: the location where the segment exchange occurs is called the “chiasmata”. I don't know about you, but I think that sounds really cool.
