Horse breeding is reproduction in horses, and particularly the human-directed process of selective breeding of animals, particularly purebred horses of a given breed. Planned matings can be used to produce specifically desired characteristics in domesticated horses. Furthermore, modern breeding management and technologies can increase the rate ...
By comparing the values for horses in a given race, a bettor can identify which horses have a more speed oriented pedigree, and which have a more stamina oriented pedigree. From a breeding point of view, stallions with a low AWD number are considered to be speed influences, and may be bred to mares whose broodmare sire has a higher number to ...
As the snails approach mating, hydraulic pressure builds up in the blood sinus surrounding an organ housing a sharpened dart. The dart is made of calcium carbonate or chitin, and is called a love dart. Each snail manoeuvres to get its genital pore in the best position, close to the other snail's body.
Two bonobos mating. The pelvic thrust is used during copulation by many species of mammals, [1] [2] [3] including humans, [4] or for other sexual activities (such as non-penetrative sex). In 2007, German scientists noted that female monkeys could increase the vigor and number of pelvic thrusts made by the male by shouting during intercourse. [5]

(Ischnura elegans) mating. In biology, mating is the pairing of either opposite-sex or hermaphroditic organisms for the purposes of sexual reproduction. Fertilization is the fusion of two gametes. [1] Copulation is the union of the sex organs of two sexually reproducing animals for insemination and subsequent internal fertilization. [2]
