Among the female parts of the flower, the gynophore is 0.8–1.6 mm long. The ovary is cylindrical, 1.0–5.0 mm long, and fused at its base to the flower's perigone. Above this is a threadlike style 1.8–7.0 mm long bearing an undivided stigma with a bumpy surface. The fruit forms as a roughly ball-shaped or cylindrical, smooth-surfaced ...
A sexual system is a distribution of male and female functions across organisms in a species. [1] [2] The terms reproductive system and mating system have also been used as synonyms. [3] Sexual systems play a key role in genetic variation and reproductive success, and may also have led to the origin or extinction of certain species. [4]
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 ...

While the layout of internal genital ducts and openings of the female genitalia depends upon the taxonomic group that insect belongs to, the internal female reproductive system of all Lepidopterans consists of paired ovaries and accessory glands which produce the yolks and shells of the eggs.
Sexual differentiation is the process of development of the sex differences between males and females from an undifferentiated zygote. [1] [2] Sex determination is often distinct from sex differentiation; sex determination is the designation for the development stage towards either male or female, while sex differentiation is the pathway towards the development of the phenotype.
Gynodioecy / ˌ dʒ ɪ n oʊ d aɪ ˈ iː s i / is a rare breeding system that is found in certain flowering plant species in which female and hermaphroditic plants coexist within a population. Gynodioecy is the evolutionary intermediate between hermaphroditism (exhibiting both female and male parts) and dioecy (having two distinct morphs: male ...
