Sex

biological sexsexesanatomical sex
Female (symbol: ♀) is the sex of an organism, or a part of an organism, that produces non-mobile ova (egg cells).
Organisms of many species are specialized into male and female varieties, each known as a sex.

Mammal

mammalsMammaliamammalian
Barring rare medical conditions, most female mammals, including female humans, have two X chromosomes.
Mammals (from Latin mamma "breast") are vertebrate animals constituting the class Mammalia, and characterized by the presence of mammary glands which in females (and sometimes males ) produce milk for feeding (nursing) their young, a neocortex (a region of the brain), fur or hair, and three middle ear bones.

Woman

womenwomanhoodfemale
The word female comes from the Latin femella, the diminutive form of femina, meaning "woman".
A woman is a female human being.

Mammary gland

mammaemammary glandsmammary
Female characteristics vary between different species with some species containing more well defined female characteristics, such as the presence of pronounced mammary glands.
Lactorrhea, the occasional production of milk by the glands, can occur in any mammal, but in most mammals, lactation, the production of enough milk for nursing, occurs only in phenotypic females who have gestated in recent months or years.

Gamete

gametesgameticreproductive cells
The ova are defined as the larger gametes in a heterogamous reproduction system, while the smaller, usually motile gamete, the spermatozoon, is produced by the male.
In species that produce two morphologically distinct types of gametes, and in which each individual produces only one type, a female is any individual that produces the larger type of gamete—called an ovum— and a male produces the smaller tadpole-like type—called a sperm.

Male

malesmasculine
The ova are defined as the larger gametes in a heterogamous reproduction system, while the smaller, usually motile gamete, the spermatozoon, is produced by the male.
Each spermatozoon can fuse with a larger female gamete, or ovum, in the process of fertilization.

Reproductive system

reproductive tractreproductivegenital system
The ova are defined as the larger gametes in a heterogamous reproduction system, while the smaller, usually motile gamete, the spermatozoon, is produced by the male.
During this process, the male inserts his erect penis into the female's vagina and ejaculates semen, which contains sperm.

Spermatozoon

spermatozoaspermsperm cells
The ova are defined as the larger gametes in a heterogamous reproduction system, while the smaller, usually motile gamete, the spermatozoon, is produced by the male.
In mammals, the sex of the offspring is determined by the sperm cell: a spermatozoon bearing a X chromosome will lead to a female (XX) offspring, while one bearing a Y chromosome will lead to a male (XY) offspring.

Isogamy

conjugationisogamousSexual conjugation
Because both gametes look alike, they cannot be classified as "male" or "female".

Lactation

lactatinglactatenurse
Only mammals produce milk.
The process can occur with all post-pregnancy female mammals, although it predates mammals.

X-inactivation

X chromosome inactivationX inactivationX-chromosome inactivation
To compensate for the difference in size, one of the female's X chromosomes is randomly inactivated in each cell of placental mammals while the paternally derived X is inactivated in marsupials.
X-inactivation (also called lyonization) is a process by which one of the copies of the X chromosome is inactivated in therian female mammals.

Intersex

ambiguous genitaliaintersexualityintersex condition
Intersex conditions can also give rise to other combinations, such as XO or XXX in mammals, which are still considered as female so long as they do not contain a Y chromosome, except for specific cases of testosterone deficiency/insensitivity in XY individuals while in the womb.
Intersex people are individuals born with any of several variations in sex characteristics including chromosomes, gonads, sex hormones, or genitals that, according to the UN Office of the High Commissioner for Human Rights, "do not fit the typical definitions for male or female bodies".

Femininity

It is distinct from the definition of the biological female sex, as both males and females can exhibit feminine traits.

Girl

A girl is a young female human, usually a child or an adolescent.

Anisogamy

Gamete size difference is the fundamental difference between females and males.

Reproduction

reproductiveprocreationreproduce
During reproduction, the male contributes either an X sperm or a Y sperm, while the female always contributes an X egg.
In these anisogamous species, the two sexes are referred to as male (producing sperm or microspores) and female (producing ova or megaspores).

Oogamy

In several lineages, this form of reproduction independently evolved to anisogamy with gametes of male and female types to oogamy.

Gender

For intersex people, who according to the UN Office of the High Commissioner for Human Rights, "do not fit typical binary notions of male or female bodies", access to any form of identification document with a gender marker may be an issue.

There is no single genetic mechanism behind sex differences in different species and the existence of two sexes seems to have evolved multiple times independently in different evolutionary lineages.
