An organism's sex category reflects its biological reproductive function rather than its sexuality or other behavior. The female sex is defined as the one which produces the larger [[gamete]] (the egg) and which typically bears the offspring. In contrast, the male sex has a smaller gamete (sperm) and rarely bears offspring. In some animals, sex may be assigned to specific structures rather than the entire organism. Earthworms, for example, are normally [[hermaphrodites]]. | An organism's sex category reflects its biological reproductive function rather than its sexuality or other behavior.
