An adult female is referred to as a ewe (/ j uː / yoo), an intact male as a ram, occasionally a tup, a castrated male as a wether, and a young sheep as a lamb. Sheep are most likely descended from the wild mouflon of Europe and Asia, with Iran being a geographic envelope of the domestication center. [ 1 ]
Monogamy: One male and one female have an exclusive mating relationship. The term "pair bonding" often implies this. This is associated with one-male, one-female group compositions. There are two types of monogamy: type 1, which is facultative, and type 2, which is obligate. Facultative monogamy occurs when there are very low densities in a ...
Freemartins, female bovines that are behaviorally masculine and lacking functioning ovaries, are commonly associated with cattle, but do occur to some extent in sheep. [6] The instance of freemartins in sheep may be increasing alongside the rise in twinning (freemartins are the result of male-female twin combinations).
In advanced groups of insects, the male uses its aedeagus, a structure formed from the terminal segments of the abdomen, to deposit sperm directly (though sometimes in a capsule called a "spermatophore") into the female's reproductive tract. Other animals reproduce sexually with external fertilization, including many basal vertebrates.

Equine anatomy encompasses the gross and microscopic anatomy of horses, ponies and other equids, including donkeys, mules and zebras.While all anatomical features of equids are described in the same terms as for other animals by the International Committee on Veterinary Gross Anatomical Nomenclature in the book Nomina Anatomica Veterinaria, there are many horse-specific ...
Male size is the determining factor in fights over a female, with the larger male emerging as the winner since their size signifies success in future offspring. [ 55 ] Other monogamous species include wolves , [ 56 ] certain species of fox , [ 57 ] [ 58 ] otters , a few hooved animals, some bats , and the Eurasian beaver .
A sex organ, also known as a reproductive organ, is a part of an organism that is involved in sexual reproduction. Sex organs constitute the primary sex characteristics of an organism. Sex organs are responsible for producing and transporting gametes , as well as facilitating fertilization and supporting the development and birth of offspring.
An udder is an organ formed of two or four mammary glands on the females of dairy animals and ruminants such as cattle, goats, and sheep. [1] An udder is equivalent to the breast in primates, elephantine pachyderms and other mammals. The udder is a single mass hanging beneath the animal, consisting of pairs of mammary glands with protruding ...
