White tigers are individual specimens of the ordinary orange tiger (Panthera tigris), with a genetic condition that causes paler colouration of the normally orange fur (they still have black stripes). The condition is well-documented in the Bengal tiger subspecies (Panthera tigris tigris or P. t. bengalensis), may also have occurred in captive Siberian tigers (Panthera tigris altaica), and has been reported historically in several other subspecies. The white individuals do not constitute a separate subspecies on their own. They have pink noses, white to cream-coloured fur, and black, grey or chocolate-coloured stripes, grey mottled skin, and ice blue eyes. White tigers are born larger, and grow faster, attaining larger adult sizes than orange tigers. This may have given them an advantage in the wild. White gene carriers, or heterozygotes, are intermediate in size. K.S. Sankhala, who was director of the New Delhi Zoo in the 1960s, said that one of the functions of the white gene may have been to keep a size gene in the population, in case it was ever needed. In the wild white tigers bred white for generations.

The condition occurs when inbreeding — usually between parents and cubs — produces offspring with two copies of a recessive gene. This is rare in nature, but with their unusual colouration, white tigers have become popular in zoos and entertainment that showcases exotic animals. For example, the magicians Siegfried and Roy are famous for having used trained white tigers in their performances. However, inbreeding often also leads to birth defects[1], which makes breeding for white colour somewhat controversial. Although it is actually possible to create white tigers without inbreeding, such cases are exceedingly rare.[citation needed]

Nevertheless, there are several hundred white tigers in captivity worldwide, and their numbers are on the increase. There are estimated to be approximately 300 white tigers alive today. There are about 75 white tigers in India. The modern population includes both pure Bengals and hybrid Bengal–Siberians, but it is unclear whether the recessive gene for white came from any of the Siberian ancestors, or only from Bengals.

Another genetic condition makes the stripes of the tiger very pale. White tigers with this condition are called snow-white.

Captive White Bengal Tiger Founders

Mohan

Mohan is the founding father of white Bengal tigers. He was captured as a cub in 1951 when maharaja Shri Martand Singh of Rewa and his hunting party in Bandhavgarh found a tigress with four 9-month-old cubs, one of which was white. All except the white cub were shot. The white cub was captured and housed at the unused Govindgarh Palace. The maharaja named it Mohan, meaning "Enchanter". The Maharaja shot a white tiger in 1948, and his father kept a male white tiger in captivity from 1915 to 1920. After it's death it was mounted and presented to the Emperor King George V, as a token of loyalty.

In 1952, Mohan was bred to a normal-coloured wild tigress called Begum ("royal consort"), and they produced several litters of orange cubs. Mohan was then bred to his daughter Radha (who carried the white gene inherited from him) and they produced a number of white cubs, including a litter of four in 1958, which included a male named Raja, and three females named Rani, Mohini, and Sukishi. These four were the first white tigers born in captivity. Raja and Rani went to the New Delhi Zoo, and Mohini was bought by the German-American billionaire John W. Kluge for $10,000, for the US National Zoo, as a gift to the children of America, in 1960. Sukeshi remained at Govindgarh Palace, where she was born, in a harem courtyard, as a mate for Mohan. The Indian government made a deal with the Maharaja, under the terms of which Raja and Rani would go to the New Delhi Zoo for free. In exchange the Maharaja's white tiger breeding would be subsidized and he would recieve a share of their cubs. The Indian Parliament used to hear reports on the progress of the white tigers, and Prime Minister Indira Gandhi and U Nu of Burma participated in public christening ceremonies for white cubs at New Delhi Zoo. President Tito of Yugoslavia visited New Delhi Zoo and asked for white tigers for Belgrade Zoo, but was refused. The government of West Bengal bought two white males from the Maharaja for Calcutta Zoo, and an orange female from the same litter of three born in 1960, accompanied them there. Calcutta Zoo had a fine specimen of a white tiger in 1920. Five zoos acquired white tigers from the Maharaja of Rewa including the Bristol Zoo in England (a brother and sister pair named Champak and Chameli in 1963) and the Crandon Park Zoo in Miami. Zoos with white tigers constituted a most exclusive club and the white tigers themselves represented a single extended family. The Maharaja was negotiating the sale of a white male as late as 1976, but the animal died. India imposed an export ban on white tigers in 1960, in an effort to preserve a monopoly, probably because Anglo-Indian naturalist E.P. Gee recommended that Govindgarh Palace, and it's white tiger inhabitants, be made a "national trust", which did'nt happen. After the export ban was imposed the Maharaja threatened to release all of his white tigers into the Rewa forest, and so he was given dispensation to sell two more pairs abroad, to offset his costs. Mohini was only allowed to leave India because President Eisenhower intervened personally with Prime Minister Nehru, to ask for the release of the United States government's white tiger. A white sister of Mohini's was brought to New Delhi the year before to show the President, who was no stranger to white tigers. Circus owner Clyde Beatty also bought a white tiger from the Maharaja in 1960, for $10,000 in a deal facilitated by Washington Zoo director T.H. Reed, which had to be cancelled because of the export ban. Dr. Reed had travelled to India to escort Mohini to Washington. Years later the Bristol Zoo needed a new breeding male and traded a white female to New Delhi Zoo for a white tiger named Roop. He was the son of Raja by his own mother Radha, born in New Delhi. Radha, and many other tigers from Govindgarh including Sukeshi, were later transfered to New Delhi. Bristol Zoo later transfered two male white tigers to Dudley Zoo. In 1951 the Maharaja placed ads in The New York Times and The Times of London, and wrote to the director of the Manchester Zoo, and probably others, offering to sell his captured white tiger cub. He wanted the princely sum of $28,000 for Mohan. The Maharaja was prevented by law from converting rupees into American dollars, and wanted the money to buy a speed boat.

Mohan died in 1969, aged almost 20. He was the last recorded white tiger born in the wild. The last white tiger reported from the wild was shot in 1958. Pushpraj Singh, the reigning Maharaja of Rewa, is asking students to sign a petition to ask the President of India to return at least two white tigers to Govindgarh Palace, as a tourist attraction.

Mohini

Mohini, a daughter of Mohan, was officially presented to President Eisenhower by John W. Kluge, in a ceremony on the White House lawn, in 1960, and went to live at the Lion House, in the National Zoo, in Rock Creek Park. Her name is the feminine of Mohan, and translates as "Enchantress". She was her father's namesake. She was a great attraction, and the zoo wanted to breed more white tigers. At the time, no more white tigers were being allowed out of India, so Mohini was mated to Sampson, her uncle and half brother. (It seems probable that financial considerations may have also precluded Washington from acquiring a second white tiger as a mate for Mohini.) After Sampson's death Mohini was bred to her son Ramana, who was then the only male white gene carrier available. This resulted in the birth of a white daughter named Rewati in 1969 and a white son named Moni in 1970. Moni died of a neurological disorder in 1971. Ramana was born in 1964 and had two litter mates-a white male named Rajkumar, who was the first white tiger born in a zoo, and an orange female named Ramani. Both died of feline distemper despite havin been vaccinated, at around one year of age. The birth of Mohini's first litter was televised in a national special. Mohini's orange daughter Kesari was born in 1966. After Moni died in 1971 the National Zoo tried to acquire an orange tiger named Ram from a zoo in southern India as a mate for Mohini. Ram was a grandson of Mohan and there was a 50% chance that he carried white genes. In 1973 an orange tiger named Poona, from a white mother and an orange father, born at New Delhi Zoo, was sent to Washington from the Brookfield Zoo and bred to Mohini and Kesari. Mohini did not conceive, but Kesari produced six orange cubs, an extraordinary number, especially for a first litter, but only one survived, a female named Marvina. (Poona also fathered litters by two other tigresses in Brookfield and 50% of these cubs would have carried the white gene.) In 1974 Marvina, Ramana, and Kesari were sent to the Cincinnati Zoo to be boarded during renovations in Washington. Ramana and Kesari produced a litter of three white and one orange cub, including a white male named Ranjit, two white females named Bharat and Priya, and an orange male named Peela. As a fringe benefit of inbreeding they were all pure-Bengal tigers, and they were the last registered Bengal tigers born in the United States. A white half sister of Mohini's bred from Mohan and his white daughter Sukishi, named Gomti and then renamed Princess, lived in the Crandon Park Zoo in Miami for about a year around 1968. Washington attorney Ralph S. Scott bought her for the Crandon Park Zoo for $35,000, and it was he that suggested that John W. Kluge, the man who introduced the white tiger to America, donate a white tiger for the Washington Zoo. Ralph S. Scott saw the white tigers in Govindgarh Palace while tiger hunting in India. A male white tiger acquired for the Crandon Park Zoo died at a railway station en route from India. He was a son of Raja and Rani, making him Princess's triple first cousin, born in New Delhi, and sold by the Maharaja of Rewa. Mohini died in 1979. The skulls and skins of Mohini and her son Rajkumar are in the Smithsonian, but are not on display. An orange brother of Mohini's named Ramar lived in Paris Zoo, and an orange aunt of hers lived in Bristol Zoo.

Tony

Tony, born in 1973 probably in August in Peru, Indiana, was the founder of many American white tiger lines, especially those used in circuses. His grandfather was a registered Siberian tiger, named Genghis, who was born at the Como Zoo in Minnesota. He was bred to a Bengal tigress named Susie, from a zoo on the east coast, at the Sioux Falls Zoo in South Dakota. Two of their cubs (Rajah and Sheba II) were bred together in a brother–sister mating, by Hungarian expatriot and self-styled "Baron" Julius von Uhl, then a trainer with the Shrine Circus, who lived in Peru, Indiana. One of the results was Tony. Tony therefore carried mixed blood and was responsible for introducing Siberian genes into previously pure Bengal lines in North America. He may also be the source of a gene for stripelessness.

In 1973 there were five white tigers in the United States: Mohini and her daughter Rewati in Washington DC, Tony, and two male first cousins of his named Bagheera and Frosty in the Hawthorn Circus, owned by of John F. Cuneo Jr. The mother of Bagheera and Frosty was a sister of Tony's mother, named Sheba III. Their father was either her registered Amur uncle and preferred mate, named Ural, or one of two of her brothers, Prince and Saber, who were also brothers to Tony's parents, which would make their offspring quadruple first cousins, if either of them fathered one or more of Sheba III's white cubs. Sheba III lived to be 26, an astonishing age for a tiger. Since most of Sheba III's litters did not include white cubs, it seems unlikely that her registered Amur uncle carried the white gene, but 50% of the cubs he did sire by Sheba III would have been white gene carriers, since they could have inherited the gene from their mother, and they would also have been three quarters Amur tiger mongrels. More likely one or both of her brothers was the culprit that fathered her white cubs. One of the two brothers was castrated before Sheba III had her last white cub, although it seems odd that a tiger which may have been fathering such valuable cubs would have been neutered.

Tony was purchased by John F. Cuneo Jr., owner of the Hawthorn Circus Corp. of Grayslake, Illinois, in 1975 at 16 months of age, for $20,000, and later bred with orange tigresses who were his first cousins, in the Hawthorn Circus, resulting in more white offspring. Tony was sent on breeding loan to the Cincinnati Zoo in 1976, to be bred to Rewati from the US National Zoo. However, Tony and Rewati did not breed, so he was bred to Mohini's orange daughter Kesari instead, resulting in a litter of four white and one orange cub, representing a mixture of the two unrelated strains. All of the white cubs from Kesari's 1976 litter by Tony were cross-eyed, as were Rewati and Bagheera. The Cincinnati Zoo retained a brother and sister pair from the litter, named Bhim and Sumita, and their orange sister Kamala. Two white males returned to the Hawthorn Circus with Tony as John Cuneo's share from the breeding loan. Bhim and Sumita became the world record parents of white cubs. Over 70 white tigers have been born at the Cincinnati Zoo, which is no longer in the white tiger business. The Cincinnati Zoo sold white tigers for $60,000 each. After 1976 only one more white tiger born at the Cincinnati Zoo was cross eyed. Crossed eyes may be reduced or eliminated through selective breeding, as it has been in Siamese cats. Critics refer to white tiger breeding as "proliferation", and the Cincinnati Zoo was derided as a "white tiger mill". The Henry Doorly Zoo in Omaha bought Tony's parents and orange sister Obie, and bred more white tigers. Obie was paired with Ranjit from the National Zoo. In 1984 Rewati was paired with Ika, from Kesari's 1976 litter, at the Columbus Zoo. By this time he was a three legged amputee retired from circus performance, put out to pasture to breed. Ika killed Rewati in the act of mating. Ika was then mated with a white tigress named Taj, who was a grand daughter of his brothers Ranjit and Bhim, and fathered white cubs in Columbus. Ika was also bred to Taj's orange mother Dolly, a daughter of Bhim, in Columbus. Isson, a white grand son of Kesari, was also dispatched to Columbus on breeding loan from the Hawthorn Circus, of Grayslake, Illinois, which eventually had 80 white tigers. In 1980 a white cub was born in the Racine Zoo in Wisconsin, from a father-daughter mating. The father killed the white cub and the mother was later bred with an orange brother of Tony. It is not known whether the Racine Zoo tigers were related to any other strains of white tigers.

Orissa White Tigers

Three white tigers were also born in the Nandankanan Zoo in Orissa, India in 1980. Their parents were an orange father–daughter pair called Deepak and Ganga, who were not related to Mohan or any other captive white tiger – one of their wild-caught ancestors would have carried the recessive white gene, and it showed up when Deepak was mated to his daughter or it could have been the result of a spontaneous mutation in Deepak. When the surprise birth of three white cubs occurred there was a white tigress already living at the zoo, named Diana, from New Delhi Zoo. One of the three was later bred to her creating another blend of two unrelated strains of white tigers. This lineage resulted in several white tigers in Nandankanan Zoo. Today the Nandankanan Zoo has the largest collection of white tigers in India. The Cincinnati Zoo acquired two female white tigers from the Nadankanan, in the hopes of establishing a line of pure-Bengal white tigers in America, but they never got a male, and didn't receive authorization from the Association Of Zoos And Aquarium (AZA)'s Species Survival Program (SSP) to breed them. The Columbus Zoo had also hoped to breed pure-Bengal white tigers, but were unable to obtain a white registered Bengal mate for Rewati from India. There were also surprise births of white tigers in the Asian Circus, in India, to parents not known to have been white gene carriers, or heterozygotes, and not known to have any relationship to any other white tiger strains. There were also white cubs born at Calcutta Zoo from orange parents related to the Orissa strain. In 1979 a heterozygote was bred to a wild caught tiger, in an Indian zoo, and produced a white cub, but the cub did'nt stay white. There have been instances of tiger and leopard cubs in the United States being born white, and then changing to normal color.

Stripeless (Snow White) Tigers

An additional genetic condition can remove most of the striping of a white tiger, making the animal almost pure white. One such specimen was exhibited at Exeter Change in England in 1820 and described by Georges Cuvier ("A white variety of Tiger is sometimes seen, with the stripes very opaque, and not to be observed except in certain angles of light")[2], Richard Lydekker ("a white tiger, in which the fur was of a creamy tint, with the usual stripes faintly visible in certain parts, was exhibited at the old menagerie at Exeter Change about the year 1820")[3], Hamilton Smith ("A wholly white tiger, with the stripe-pattern visible only under reflected light, like the pattern of a white tabby cat, was exhibited in the Exeter Change Menagerie in 1820") and John George Wood ("a creamy white, with the ordinary tigerine stripes so faintly marked that they were only visible in certain lights".) Edwin Landseer also drew this tigress in 1824.

The modern strain of snow white tigers came from repeated brother–sister matings of Bhim and Sumita at Cincinnati zoo. The gene involved possibly came from the Siberian tiger, via their part-Siberian ancestor Tony. Continued inbreeding appears to have caused a recessive gene for stripelessness to show up. About one fourth of Bhim and Sumita's offspring were stripeless. Their striped white offspring, which have been sold to zoos around the world, may also carry the stripeless gene.

Because Tony is present in many white tiger pedigrees, the gene may also be present in other captive white tigers. As a result, stripeless whites have occurred in zoos as far afield as the Czech Republic, Spain and Mexico. Stage magicians Siegfried and Roy were the first to attempt to breed selectively for stripelessness; they own snow white Bengal tigers taken from Cincinnati Zoo (Tsumura, Mantra, Mirage and Akbar-Kabul) and Guadalajara, Mexico (Vishnu and Jahan), and a stripeless Siberian tiger called Apollo.

In 2004, a blue-eyed, stripeless white tiger was born at a wildlife refuge in Alicante, Spain. Its parents are normal orange Bengals. The cub was named Artico ("Arctic").

Genetics & Albinism

Contrary to popular belief, white tigers are not albinos; true albino tigers would have no stripes. The stripleless white tigers known today only have very pale stripes. There is, in fact, no evidence of true albinisms in modern tigers.

Part of the confusion is due to the misidentification of the so-called chinchilla gene (for white) as an allele of the albino series (publications prior to the 1980s refer to it as an albino gene). The mutation is recessive to normal color, which means that two orange tigers carrying the mutant gene may produce white offspring, and white tigers bred together will produce only white cubs. The stripe color varies due to the influence and interaction of other genes.

While the inhibitor ("chinchilla") gene affects the color of the hair shaft, there is a separate "wide-band" gene affecting the distance between the dark bands of colour on agouti hairs.Robinson, Roy; et al. (1999). Genetics for Cat Breeders and Veterinarians. Butterworth-Heinemann. ISBN 978-0750640695. {{cite book}}: Explicit use of et al. in: |last= (help) An orange tiger who inherits two copies of this wide-band gene becomes a golden tabby; a white who inherits two copies becomes almost or completely stripeless. Inbreeding allows the effect of recessive genes to show up, hence the ground and stripe colour variations among white tigers.

As early as 1907, naturalist Richard Lydeker doubted the existence of albino tigers.[4] However, we do have a report of true albinism: in 1922, two pink-eyed albino young were shot along with their mother at Mica Camp, Tisri, in Cooch Behar District, according to Victor N Narayan in a ”Miscellaneous Note” in the Journal of the Bombay Natural History Society. The albinos were described as sickly-looking sub-adults, with extended necks and pink eyes.

Inbreeding depression

Because of the extreme rarity of the white tiger allele in the wild[citation needed], the breeding pool is limited to the small number of white tigers in captivity, which all descend from a common ancestor. Inbreeding between these tigers often leads to defects. Due to the high market value for white tigers, unscrupulous breeders will still inbreed white tigers to ensure the offspring also exhibit the recessive gene. Some animal rights activists have called for a halt to the breeding of white tigers altogether.

Outside of India, highly inbred white tigers are prone to crossed eyes (strabismus) due to incorrectly routed visual pathways in the brain (when stressed or confused all white tigers cross their eyes according to tiger trainer Andy Goldfarb), star-gazing and postural problems. A weakened immune system is directly linked to reduced pigmentation. White tigers react strangely to anesthesia due to their inability to synthesize the tyrosinase enzyme, a trait shared with true albinos. Strabismus is associated with white tigers of mixed Bengal/Siberian ancestry. Only one pure Bengal white tiger was reported to be cross-eyed: Mohini's daughter Rewati. Strabismus is directly linked to the white gene and is not a separate result of inbreeding. Siamese cats exhibit the same visual pathway abnormality found in white tigers, and are also known to be cross eyed in some instances. White tigers, Siamese cats, and Himalayan rabbits have enzymes in their fur which react to temperature, making their fur darken in cold. This is why Siamese cats and Himalayan rabbits are darker on their nose, ears, legs, and tail, where the cold penetrates more easely. K.S. Sankhala, who was director of the New Delhi Zoo in the 1960s, observed that white tigers are always whiter in Rewa, even when they are born in New Delhi and returned to there. Rewati also had a crooked spine, shortened limbs, and her reproductive cycle was irregular, making her a poor candidate for breeding. This may be why the National Zoo did not elect to breed her with Poona, while he was on breeding loan to Washington in 1973, but because of the rarity and demand for white tigers she was later bred by Robert Baudy, in Center Hill, Florida, to an unrelated orange Amur tiger, but did not conceive. Rewati also lived at the Bronx Zoo for several years and they may have attempted to breed her. It has been possible to expand the white gene pool by outcrossing white tigers with unrelated orange tigers and then using the cubs to produce more white tigers. Poona was the result of an outcross between a white tiger and an unrelated orange tiger at the New Delhi Zoo. Ranjit, Bharat, Priya, and Bhim were all outcrossed; in some instances to more than one unrelated tiger. Bharat was bred to an unrelated orange tiger named Jack, from the San Francisco Zoo, and had an orange daughter named Kanchana, born in Washington. Bharat and priya were also bred with an unrelated orange tiger from Knoxville Zoo, and Ranjit was bred to this tiger's sister, also from Knoxville Zoo. Bhim fathered several litters by an unrelated orange tigress named Kimanthi, at the Cincinnati Zoo. Ranjit had several mates at the Omaha Zoo. The draw backs are the loss of a generation and the production of surplus cubs. Perhaps the mongrelization of white tigers has been a mixed blessing since, although the introduction of Amur genes into the white strain has further delegitemized white tigers for zoo conservation purposes, it's possible that hybrid vigor has counteracted inbreeding depression and created healthier bloodlines.

Mohini was checked for Chediak-Higashi Syndrome, but the results were inconclusive. This is similar to albino mutations, and causes bluish lightening of the fur color, crossed eyes, and prolonged bleeding in the event of surgery or injury, the blood is slow to coagulate, in domesticated cats. Other genetic problems include shortened tendons of the forelegs, clubfoot, central retinal degeneration (reported in a single male white tiger in the Oklahoma City Zoo) , kidney problems, arched or crooked backbone and twisted neck. Reduced fertility and miscarriages, noted by ”tiger man” Kailash Sankhala, were attributed to inbreeding depression. Some of the white tigers born to North American lines have bulldog faces with a snub nose, jutting jaw, domed head and wide-set eyes with an indentation between the eyes. However, some of these traits have also been linked to poor diet. The white gene is recessive, and therefore must be inherited from both parents, to produce a white tiger. Inbreeding is a conscious strategy to promote homozygosity in white tigers. There's really no such thing as a white gene. White tigers carry orange genes which are "switched off."

Historical records

While the modern population descend from Rewan tigers, white tigers have been recorded as far afield as China and Korea, Nepal, Myanmar, the Malay Peninsula, Sumatra and Java. Historically, white tigers have been reported in northern China, in the geographic range of the Siberian tiger, and in the Indo-Chinese, Sumatran and Javan subspecies, but not among South China, Caspian or Bali tigers.

In some regions, the animal forms part of local tradition. In China, it was revered as the god of the West, Baihu. In South Korea, a white tiger will sometimes be represented on the taeguk emblem on the flag – the symbolising evil, opposite the green dragon for good. In Indian superstition, the white tiger was the incarnation of a Hindu deity, and anyone who killed it would die within a year. Sumatran and Javan royalty claimed descent from white tigers, and the animals were regarded as the reincarnations of royalty.

White tigers with dark stripes were recorded in the wild in India during the Mughal Period (1556–1605). A painting from 1590 of Akbar on hunting near Gwalior depicts four tigers, two of which appear white. As many as 17 instances of white tigers were recorded in India between 1907 and 1933 in several separate locations: Orissa, Bilaspur, Sohagpur and Rewa.

Between 1892 and 1922, white tigers were routinely shot in India in places such as Orissa, Upper Assam, Bilaspur, Cooch Behar and Poona. Pollock (1900) reported white tigers from Burma and the Jynteah hills of Meghalaya. In the 1920s and 30s, fifteen white tigers were killed in Bihar, and more were shot in other regions. On 22 January 1939, the Prime Minister of Nepal shot a white tiger at Barda camp in Terai Nepal. The last observed wild white tiger was shot in 1958, and the mutation is considered extinct in the wild [citation needed]. The slaughter of so many orange tigers may have killed the carriers of the mutant gene.
