Zebras reproduce sexually: The male zebra, which is called a stallion, mounts a female zebra, which is called a mare, and deposits sperm in the mare's vagina via the stallion's penis. If the mating is successful, the mare births a single foal 12 to 13 months later.Know More
Zebra herds typically consist of a stallion and several mares, comprising a group known as a harem. Stallions compete with one another to lay claim to a harem. Once a stallion emerges victorious, his claim is challenged only when other stallions perceive weakness due to disease or injury.
Stallions reach sexual maturity at 4 years old, while mares reach sexual maturity between 2 and 4 years old. Like other equine species, a zebra mare in estrus — that is, in heat — often signals her willingness to breed with a stallion by "winking" the labia, or turning them outward.
The long gestation period observed in zebras allows a foal to develop sufficiently that, within minutes of being born, it is able to stand. In spite of this developmental advantage, infant mortality among zebra foals is approximately 50 percent. If the foal reaches maturity, the average expected lifespan in the wild is between 20 and 25 years.Learn more about Animal Reproduction
Men possess external genitalia (the penis, scrotum and testes) for the production and delivery of sperm, and women possess internal genitalia (the vagina, uterus and ovaries) for the production of eggs and the development of human embryos. Most physiological differences between men and women occur due to differences in the endocrine systems during critical periods of development, such as fetal growth and puberty.Full Answer >
Bears are mammals and therefore reproduce sexually, The male deposits sperm from his penis into the vagina of the female bear. If the egg becomes fertilized, the female bear gives birth to live young. The average number of cubs in a black bear litter is three, but first-time mothers usually only give birth to one cub.Full Answer >
The standard mare gestation length is from 320 to 362 days after the date of breeding, and on average, most mares will foal, or give birth, 330 to 345 days after a successful breeding. However, it is common for a mare to successfully give birth in a later period than the average range.Full Answer >
Male zebras are called stallions. Females are called mares, and young zebras are called foals. In zebra herds, stallions alert the herd to predators and serve as guardians.Full Answer >
