  1. 1MuleMuleThe classic hybrid: a male donkey crossed with a female horse. A mule has 63 chromosomes, 32 from the horse and 31 from the donkey, and that odd number makes it almost always infertile, though rare pregnancies have occurred naturally. People keep breeding them because the cross works. Mules are…0
  2. 2HinnyHinnyThe reverse of the mule: a male horse crossed with a female donkey. Hinnies are less common, generally smaller, with shorter ears and a lighter head, and most reports describe them as sterile. The puzzle is why a hinny differs from a mule at all when both carry the same mix of horse and donkey…0
  3. 3ZebroidZebroidZorse A zebra stallion crossed with a horse mare. The stripes rarely cover the whole body and are sometimes confined to the legs, laid over the horse's coat. Zorses are sterile, and zebra hybrids tend to be more temperamental than horses and can be hard to handle, which keeps them a curiosity…0
  4. 4DzoDzoA yak crossed with domestic cattle, kept by herders in Tibet and Mongolia. Strictly, dzo is the male and dzomo the female, and only the females are fertile. Hybrid vigor is the whole point here. These animals are larger and stronger than the local yaks or cattle and are thought to give more milk…0
  5. 5BeefaloBeefaloA cattle breed with a share of American bison ancestry, defined by the American Beefalo Association as at least five-eighths cattle and at most three-eighths bison. Cattle and bison were first deliberately crossed in the mid-19th century, and Bud Basolo developed the modern breed in the 1970s.…0
  6. 6Cama (animal)Cama (animal)A male dromedary camel crossed with a female llama, first born on January 14, 1998, at the Camel Reproduction Centre in Dubai. It only works by artificial insemination and only in that direction: a camel can weigh up to six times as much as a llama, and llama sperm has never produced a viable calf…0
  7. 7LigerLigerA male lion crossed with a tigress, and bigger than either parent. In 2013, Guinness World Records named a liger called Hercules the largest living cat, at 922 pounds (418.2 kg). Imprinted genes, which act differently depending on which parent passed them on, may explain the size. Male ligers are…0
  8. 8TigonTigonA male tiger crossed with a lioness, the liger's reverse. Where the liger outgrows both parents, the tigon inherits growth-limiting genes and does not exceed their size, a neat demonstration that which parent is which matters. As with ligers, males are sterile and females fertile: Rudrani, a tigon…0
  9. 9Panthera hybridPanthera hybridLeopon A leopard crossed with a lioness. The result is spotted like a leopard, though the spots on its sides are smaller and closer set. The first documented leopon was bred at Kolhapur, India, in 1910, and leopons occur only in captivity. It belongs on this list as the rarer cousin of the liger…0
  10. 10Savannah catSavannah catA domestic cat breed that began as an African serval crossed with a house cat. Judee Frank made the first cross on April 7, 1986, and TICA accepted the Savannah as a registered breed in 2001. The early generations are hybrids in the full sense. First-generation kittens are very difficult to…0
