The male parent of a horse, a stallion, is commonly known as the sire and the female parent, the mare, is called the dam. [1] Both are genetically important, as each parent genes can be existent with a 50% probability in the foal. Contrary to popular misuse, "colt" refers to a young male horse only; "filly" is a young female.
Light, oriental horses such as the ancestors of the modern Arabian, Barb, and Akhal-Teke were used for warfare that required speed, endurance, and agility. [16] Such horses ranged from about 12 hands (48 inches, 122 cm) to just under 15 hands (60 inches, 152 cm), weighing approximately 360 to 450 kilograms (800 to 1,000 lb). [17]
Polygynandry is a mating system in which both males and females have multiple mating partners during a breeding season. [1] In sexually reproducing diploid animals, different mating strategies are employed by males and females, because the cost of gamete production is lower for males than it is for females. [2]

Free-roaming mustangs (Utah, 2005). Horse behavior is best understood from the view that horses are prey animals with a well-developed fight-or-flight response.Their first reaction to a threat is often to flee, although sometimes they stand their ground and defend themselves or their offspring in cases where flight is untenable, such as when a foal would be threatened.
Extra pair coupling refers to male and females mating with several mates but only raising offspring with one mate. The male may not be related to all of the offspring of his main mate, but some offspring are being raised in other broods by other males and females, thereby offsetting any limitation of monogamy. [14]
In zoology, copulation is animal sexual behavior in which a male introduces sperm into the female's body, especially directly into her reproductive tract. [ 1 ] [ 2 ] This is an aspect of mating . Many aquatic animals use external fertilization , whereas internal fertilization may have developed from a need to maintain gametes in a liquid ...
Polygyny is where one male mates with several females in a breeding season (e.g., lions, deer, some primates, and many systems where there is an alpha male). [1] A common example of polyandrous mating can be found in the field cricket ( Gryllus bimaculatus ) of the invertebrate order Orthoptera (containing crickets, grasshoppers, and ...
