Estimations show that around one in 10,000 wild tiger A white tiger is caused by the occurrence of a double recessive allele in the genome. The gene for white coating is quite common among Bengal tigers, but the natural birth of a white Bengal tiger is still a very rare occasion in the wild, where white tigers are not bred selectively. They are instead the result of Siberian tigers breeding with Bengal tigers. The famous white Siberian tigers found in captivity are actually not pure Siberian tigers.
More research is necessary before scientists can fully understand the genetic make up of the Siberian tiger. The wild Siberian tiger population nearly went extinct during the middle of the 20th century, so it is also possible that the Siberian tigers carrying the gene for white coating died out during this period. It is quite possible that the gene for white coating does not exist in the Siberian tiger population, since no pure white Siberian tigers have been born in captivity even though the Siberian tiger has been extensively bred during the last few decades. The existence of pure white Siberian tigers has not been scientifically proven, despite occasional reports of sightings of white tigers in the regions where wild Siberian tigers live.
