Most women have the karyotype 46, XX, but around one in a thousand will be 47, XXX, and one in 2500 will be 45, X.
This contrasts with the typical male karotype of 46, XY; thus, the X and Y chromosomes are known as female and male, respectively.
The Venus symbol also represented femininity, and in ancient alchemy stood for copper.

The breast evolved from the sweat gland to produce milk, a nutritious secretion that is the most distinctive characteristic of mammals, along with live birth.
In mature women, the breast is generally more prominent than in most other mammals; this prominence, not necessary for milk production, is probably at least partially the result of sexual selection.
Women (in contrast with male humans, or men) typically have two X chromosomes, a uterus, a vagina, and mammary glands (as with all female mammals).
Women with typical genetic development undergo regular menstruation when not pregnant and are usually capable of giving birth from puberty until menopause.
Womanhood is the period in a human female's life after she has passed through childhood and adolescence, generally around age 18.
The word woman can be used generally, to mean any female human or specifically, to mean an adult female human as contrasted with girl.In Old English, wīfmann meant "female human", whereas wēr meant "male human".Mann or monn had a gender-neutral meaning of "human", corresponding to Modern English "person" or "someone"; however, subsequent to the Norman Conquest, man began to be used more in reference to "male human", and by the late 13th century had begun to eclipse usage of the older term wēr.The word girl originally meant "young person of either sex" in English; The term girl is sometimes used colloquially to refer to a young or unmarried woman; however, during the early 1970s, feminists challenged such use because the use of the word to refer to a fully grown woman may cause offence.In particular, previously common terms such as office girl are no longer widely used.Because humans inherit mitochondrial DNA only from the mother's ovum, genetic studies of the female line tend to focus on mitochondrial DNA.Tags: Adult Dating, affair dating, sex dating
