Han people believe that white tiger is the king of beasts. When a tiger live to 500 years old and they will incarnation is white, has become a fetish - only in Dili Wangxiu De, flourishing political time will appear. White tiger, is one of the Quartet of God, rage, bit west seven places. In Chinese culture deeply influenced East Asia, the white tiger is a symbol of good luck.
In nature among white tiger occasionally occur. Peking University Professor Luo said gold was found, the white tiger is the reason why is because the SLC45A2 gene mutations. This gene affects hair synthetic yellow and red pigment and the skin which thus becomes white tiger however, it has little influence black pigment, thus, still black stripes. The mutation frequency of occurrence is very low, but naturally occurring, can not be considered a genetic defect. Wild white tigers can live to adulthood. 1950s, and shot wild white tiger records. This mutation is not limited to the Bengal tiger subspecies, the Siberian tiger has also appeared in white individuals.
If only this, but rather a kind of like the white tiger king cheetah concern mutants, because such mutations is too little met. However, breeding the white tiger, but it is of no benefit wildlife conservation behavior.
Today, the white tiger in the zoo, are well-known male tiger Mohan (Mohan, meaning "illusionist") children. Not as many articles as written, Mohan is not the first record of human white tigers before it, the Indian maharaja monarch has been raised several of the white tigers.
May 1951, the Indian maharaja of Rewa Shri Martand Singh Maharaja received reports of a tigress was found in a four whelp white. Maharaja immediately started hunting. According to records, it would only slow tigress approached Maharaja and his guests hiding place, almost did not cause any threat was shot. Maharaja's hunting no plan, they killed two cubs, fortunately lucky, those two are not white.
Mohan smaller than its brothers may be strong, but not too good chance. It fled into the jungle, but because under hunger, frustration back at his mother's corpse killing prey, then was discovered, hurriedly fled into the rock crevices. He was recruited over a carpenter, made a hole in the cage. Eventually, because of hunger and thirst, Mohan into the trap.
Tiger is an amazing creature, especially the white tiger. Maharaja Mohan holds, of course, is a valuable commodity. There was a magazine reported: "King, 28 years old this year, asking $ 28,000 selling his white tiger."
Mohan began its "affair." At that time, people can not find another white tiger Mohan and pairing, then captured the only normal coat vixen and Mohan pairing. But Maharaja apparently never studied genetics, he did not know what recessive gene that has been so Mohan and its "wife" mate, then, at the beginning Mohan offspring are normal coat color heterozygotes. Later, perhaps another soil Bomba Rhoda Maharaja awoke parties, the Maharaja had recorded: "The Reva was frustrated, I told him the answer: It should allow Mohan incest" So, Mohan beginning and its daughter Rada (Rahda) mating, and finally gave birth to white offspring.
Breeding this way, in biology called "backcrossing", and can not be equated to the human society incest. After that, Mohan and its children and grandchildren, in the human intervention launched a large number of "genetic experiments", the white tiger family was built up. White white tiger these genes are Mohan from India, it is the Mesmer, will be a symbol of good fortune down to the ground.
(Larger point here )
After that, things messy.
Backcross is a high risk thing. Inbreeding, there are both more likely to be the same recessive gene, so the more likely the offspring homozygous recessive disease. Therefore, in breeding them, for the health of future generations, we should try to make the relationship a little further hybridized. The figure is the initial Mohan family lineage, we can see that hybrid is still very cautious.
White Tiger's value can be measured by money. So, for faster access to new tiger, not later on nobody pedigree lineage of. A variety of genetic diseases have emerged, such as the immune system defects, scoliosis, hip dysplasia, etc., plaguing Mohan considerable number of children and grandchildren. Malformations, stillbirths are not uncommon. The problem itself is through scientific breeding way to avoid. For example, the introduction of a normal coat and white tiger tiger for parental mating, and then gave birth to a tiger white tiger lineage distant hybridization, can repair genes to a certain extent, the introduction of new blood. But for efficiency, whether it be business people science unscientific.
This is just one of the problems of the white tiger.
In the zoo, the tiger is the focus of attention. They often occupy the best houses, the best facilities, occupy the most attention. Under their shadow, leopard, clouded leopard, snow leopard, lynx, golden cat is normal even lions, tigers are not given due attention, crowded in a small cage them. But compared to these animals, white tiger deserve to have so much resources and attention.
why?
Zoo has two of the most basic objectives: the conservation, breeding of rare animals, the public about wildlife conservation education. We can say that the measure of a zoo is science, the attitude of the White Tiger is the best indicator.
White tiger is not a separate species, not even a separate subspecies, they are the Bengal tiger. White Tiger get attention, simply because one (or several) genes. Compared to the general Bengal tiger, white tiger protection urgency is actually about the same, even in the tiger family, as well as Sumatran tigers, Malayan tigers and these more rare Indochinese tiger subspecies. Compared to those who cherish more the need to protect animals, white tiger occupy space and money can actually use more scientific. Beijing Zoo is an example: to White Tiger so good facilities, more rare leopard, but the need to protect local production is in North China leopard, all crowded in a small cage in panting.
In order to promote its business, a lot of white tiger zoo has been touted high, which can lead to the failure of public education. Guangzhou Changlong Zoo is the case, this zoo is a zoo lovers make very tangled exist. As a result, they are indeed very rich, Yuanshe done very beautifully displayed matchless gorgeous animals, the zoo is the best example of the but on the other hand, they do a lot of things very unscientific, single Changlong said the white tiger breeding is done on massive, shocking.
White Tiger, is not a presence should not exist. White tiger breeding to the money is a normal market behavior, if it can avoid genetic diseases, to ensure the White Tiger's own animal welfare, this business should not be criticized. If the zoo overly treat white tiger, science promotion, more attention needs to focus on animals show white tiger display also lacks.
However, these assumptions do not exist.
White tiger presence, as only big cat rescue center following the adoption of small poor as substantially deformed.
