An organism's sex is female (symbol: ♀) if it produces the large non-motile ovum (egg cell), the type of gamete (sex cell) that fuses with the male gamete (sperm cell) during sexual reproduction.

The symbol of the Roman goddess Venus is used to represent the female sex in biology. It also stands for the planet Venus and is the alchemical symbol for copper. A female has larger gametes than a male. Females and males are results of the anisogamous reproduction system, wherein gametes are of different sizes (unlike isogamy where they are the same size). The exact mechanism of female gamete evolution remains unknown.

In species that have males and females, sex-determination may be based on either sex chromosomes, or environmental conditions. Most female mammals, including female humans, have two X chromosomes. Female characteristics vary between different species, with some species having pronounced secondary female sex characteristics, such as the presence of pronounced mammary glands in mammals.
