In species that use the ZW sex-determination system the offspring genotype may be one of ZW (female), [28] [29] ZZ (male), or WW (non-viable in most species, [31] but a fertile, [dubious – discuss] viable female in a few, e.g., boas). [31] ZW offspring are produced by endoreplication before meiosis or by central fusion.
The symbol of the Roman goddess Venus is used to represent the female sex in biology. [1] An organism's sex is female (symbol: ♀) if it produces the ovum (egg cell), the type of gamete (sex cell) that fuses with the male gamete (sperm cell) during sexual reproduction. [2] [3] [4] A female has larger gametes than a male.
For example fecundity is the potential to for a female to become pregnant and carry that pregnancy to a live birth in demography, while in clinical medicine it refers to actual production of live offspring.

The human female reproductive system is made up of the internal and external sex organs that function in the reproduction of new offspring. The reproductive system is immature at birth and develops at puberty to be able to release matured ova from the ovaries , facilitate their fertilization , and create a protective environment for the ...
A daughter is a female offspring; a girl or a woman in relation to her parents. Daughterhood is the state of being someone's daughter. The male counterpart is a son. Analogously the name is used in several areas to show relations between groups or elements. From biological perspective, a daughter is a first degree relative.
Anisogamy (the opposite of isogamy) comes from the ancient Greek negative prefix a(n)-(alpha privative), the Greek adjective isos (meaning equal) and the Greek verb gameo (meaning to have sex/to reproduce), eventually meaning "non-equal reproduction" obviously referring to the enormous differences between male and female gametes in size and abilities. [10]
This list of related male and female reproductive organs shows how the male and female reproductive organs and the development of the reproductive system are related, sharing a common developmental path. This makes them biological homologues. These organs differentiate into the respective sex organs in males and females.
