These processes are called mitosis and meiosis. Mitosis is ordinary cell division. Meiosis is the process by which sperm and egg cells are formed in a manner that allows them to join together to start a new life. Detailed descriptions of these can be found in any standard textbook on ...

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?

Meiosisis the process by whichgametes(sex cells) are generated in organisms thatreproduce sexually. Gametes are produced in male and femalegonadsand contain one-half the number ofchromosomesas the original cell. Newgenecombinations are introduced in a population through thegenetic recombinationthat occur...
