Meanings
Adjective
relating to meiosis or the cell division that produces sex cells
Beyond the definition
The word "meiotic" comes from meiosis, a special kind of cell division that is important in sexual reproduction. Most cells in the body divide in the usual way, but cells that make sperm or egg cells go through meiosis instead. Anything connected to that process can be called meiotic: the stages, the cells involved, or the structures that help it happen. So you would use the word when talking about genetics, reproduction, or cell biology. For example, a "meiotic spindle" is a structure that forms during this kind of division.
"Meiotic" describes anything pertaining to meiosis, the process of cell division that produces gametes—sperm cells in males and egg cells in females. Unlike typical cell division (mitosis), which creates identical copies, meiosis reduces the number of chromosomes by half. This is vital because when a sperm and egg fuse during fertilization, they restore the full chromosome count, ensuring offspring inherit genetic material from both parents.
The term "meiotic" isn't something you'd use in everyday conversation; it's firmly rooted in the world of biology, genetics, and reproductive science. You might encounter it when reading about meiotic drive (where certain genes increase their chances of being passed on), meiotic recombination (the swapping of genetic material that creates diversity), or meiotic errors (mistakes during division that can lead to genetic disorders).
For example, a researcher might study "meiotic checkpoints"—control mechanisms ensuring the process happens correctly. Or they might investigate how environmental factors affect "meiotic progression." Essentially, if it's connected to the intricate dance of chromosome separation and gamete formation, it's likely meiotic. It's a specialized term that unlocks an understanding of how life perpetuates itself through generations.

Cell division
During meiotic division, the developing egg cell reduces its number of chromosomes.
