research revealed that wild hybrids were also present in ancient times. The mitochondrial genomes of the snow leopard and the lion were more similar to each other than to other ''Panthera'' species, indicating that at some point in their history, the female hybrid progeny of male ancestors of modern snow leopards and female ancestors of modern lions interbred with male ancestors of modern snow leopards.
History
In theory, lions and tigers can be matched in the wild and give offspring. In reality, there may be no natural born tigon or liger in the world, as lions and tigers are separated both geographically and by behavioral differences. In England, African lions and Asian tigresses have been successfully mated, and three lion-tiger hybrid cubs were born in Windsor in 1824, which is probably the earliest record of captive-bred ligers.
The three cubs were then presented to

A leguar or lepjag is the hybrid of a male leopard and a female jaguar. The terms jagulep and lepjag are often used interchangeably, regardless of which animal was the sire. Numerous lepjags have been bred as animal actors, as they are more tractable than jaguars.
The 19th century zoologist A.D. Bartlett stated: "I have, more than once, met with instances of the male jaguar (''P. onca'') breeding with a female leopard (''P. pardus''). These hybrids were also reared recently in Wombell's well-known travelling collection. I have seen some animals of this kind bred, between a male black jaguar and a female Indian leopard:-the young partook strongly of the male, being almost black."

Scherren continued, "The same cross, but with the sexes reversed, was noted, by Professor Sacc (F) of Barcelona Zoo (Zoolog. Gart., 1863, 88). "The cub, a female, was grey. She is said to have produced two cubs to her sire; one like a jaguar, the other like the dam. Herr Rorig expressed his regret that the account of the last two cases mentioned lacked fullness and precision."

There is a claimed sighting of a lion × black jaguar cross (male) and a tiger × black jaguar cross (female) loose in Maui, Hawaii. There are no authenticated tiger/jaguar hybrids and the description matches that of a liger. The alleged tiger × black jaguar was large, relatively long-necked (probably due to lack of a ruff or mane) with both stripes and "jaguar-like" rosettes on its sides. The assertion of hybrid identity was due to the combination of black, dark brown, light brown, dark orange, dark yellow and beige markings and the tiger-like stripes radiating from its face. It is more likely to have been a released liger, since these are very large and have a mix of rosettes (lion juvenile markings) and stripes and can have a brindled mix of colors exactly as described (their markings are extremely variable).

Natural History Society. It was a cross between a large leopard and a lioness. Two cubs were born, one of which died aged 2.5 months, and the other was still living when Pocock described it in 1912. Pocock wrote that it was spotted like a leopard, but that the spots on its sides were smaller and closer set than those of an Indian leopard and were brown and indistinct, like the fading spots of a juvenile lion. The spots on the head, spine, belly and legs were black and distinct. The tail was spotted on the topside and striped underneath and had a blackish tip with longer hairs. The underside was dirty white, the ears were fawn and had a broad black bar, but did not have the white spot found in leopards.
Another lion-leopardess hybrid was born in Florence, Italy called lionard or lipard (/'laɪpəd/ or /'laɪpərd/).
Leopard and tiger hybrids
The name ''dogla'' is a native Indian name used for a supposedly natural hybrid offspring of a male leopard and a female tiger (tigress). Indian folklore claims that large male leopards sometimes mate with tigresses, and anecdotal evidence exists in India of offspring resulting from leopard to tigress matings. A supposed ''dogla'' was reported in the early 1900s.
Tiger-leopardess hybrids have supposedly appeared many times. Frederick Codrington Hicks recorded that the weight of these creatures varied from 50 pounds to the weight of a tigress. In addition, in September 1965, a "leoger" skin was supposedly put on sale. There are some more documentations of this hybrid, but most of them are just of strange-looking skins that could also be attributed to genetic mutations. Most of these reports are probably hoaxes or misinterpretations, which makes it hard for scientists to learn about tiger-leopardess hybrids, but at least a part of the claims are true or in part true, such as the ones made by Frederick Codrington Hicks.
K Sankhala's book ''Tiger'' refers to large, troublesome leopards as ''adhabaghera'', which he translated as "bastard", and suggests a leopard/tiger hybrid (the reverse hybrid is unlikely to arise in the wild state, as a wild male tiger would probably kill rather than mate with a female leopard). Sankhala noted there was a belief amongst local people that leopards and tigers naturally hybridise.
From "The Tiger, Symbol Of Freedom", edited by Nicholas Courtney: "Rare reports have been made of tigresses mating with leopards in the wild. There has even been an account of the sighting of rosettes; the stripes of the tiger being most prominent in the body. The animal was a male measuring a little over eight feet .44 m" This is the same description as given by Hicks.
The 1951 book ''Mammalian Hybrids'' reported tiger/leopard matings were infertile, producing spontaneously aborted "walnut-sized fetuses".
A tigard is the hybrid offspring of a tiger and a leopardess. The only known attempts to mate the two have produced stillborns.
In 1900, Carl Hagenbeck crossed a female leopard with a Bengal tiger. The stillborn offspring had a mixture of spots, rosettes and stripes. Henry Scherren wrote, "A male tiger from Penang served two female Indian leopards, and twice with success. Details are not given and the story concludes somewhat lamely. 'The leopardess dropped her cubs prematurely, the embryos were in the first stage of development and were scarcely as big as young mice.' Of the second leopardess there is no mention."
Lion and tiger hybrids
The hybrids resulting from crossbreeding between lions and tigers are known as tigon ( /ˈtaɪɡən/) and liger ( /ˈlaɪɡər/). The second generation hybrids of liger or tigon are known as liliger, tiliger, litigon and titigon. The tigon (''Panthera tigris X leo''), also known as tiglon ( /ˈtaɪɡlən/) is an offspring of a male tiger (''Panthera tigris'') and a female lion (''Panthera leo''). A liger is distinct from tigon (''Panthera leo X tigris''), as a hybrid of female tiger and male lion.
Professor Valentine Bail conducted a long observation and recording of some lion-tiger hybrids, those lion-tiger are owned by Mr. Atkins and his zoo:
The early record lion-tiger hybrid was mainly tigons, in ''At Home In The Zoo'' (1961), Gerald Iles wrote "For the record I must say that I have never seen a liger, a hybrid obtained by crossing a lion with a tigress. They seem to be even rarer than tigons."

results from the lack of certain genes that limit the growth of lions. The male lion's genes tend to maximize the growth of its progeny, as the larger size represents greater competitiveness. In order to control the size of the offspring within a certain range, the growth-inhibiting gene of the lioness will offset the growth-maximizing gene of the male lion. The genes of a female tiger, however, are not adapted to limiting growth, which allows ligers to grow far larger and heavier than either parent. In general, most ligers grow more than in length and weigh more than . According to the

(however, inversely). A tigon is approximately twice as light as liger.
Appearance
Ligers and tigons look similar to their parents, only bigger or smaller. Their teeth are about two inches long. They have the genetic components of tigers and lions; therefore, they may be very similar to their parent species and can be difficult to identify. Their coloring ranges from gold to brown to white, and they may have spots or stripes. Adult male ligers usually have smaller manes than male lions.
Longevity
A liger called Samson died at the age of thirteen in 2006. Shasta, a female liger, was born in the Hogle Zoo in Salt Lake City in 1948, and died in 1972. She lived for 24 years. Many claim that ligers are short-lived, but according to the survey, such a conclusion is still uncertain. A male tigon owned by Atkins born on July 19, 1833, lived for 10 years.
Fertility
Guggisberg said ligers and tigons were thought to be invariably

Sterile or sterility may refer to:

* Sterile (archaeology), a sediment deposit which contains no evidence of human activity

. The first hybrid of a hybrid, a cub mothered by a liger, was discovered at the Munich-Hellabrunn Zoo in 1943. The birth of a second generation of hybrids proved that the biologists were wrong about tigons' and ligers' fertility; it now seems that only male lion-tiger hybrids are sterile.
Zoo animals
By 2017, roughly more than 100 ligers were thought to exist; however, only a few tigons still exist, as they are more difficult to breed. Moreover, ligers are more likely to attract tourists, so zoos prefer to breed ligers as opposed to tigons.
Some zoos claim they breed ligers or tigons for conservation, but opponents believe that it is meaningless to preserve hybrids that do not exist in the wild.
