White bengal tigers are rare in nature and occur naturally in about 1 in 10,000 births. The lack of pigment is caused by a double dose of a recessive gene. Both parents have to carry the gene. They are bred in captivity, for the white trait, as a spectacle to boost attendance at zoos or Las Vegas style shows. Inbreeding for the white trait comes along with strabismus (crossed eyes) and larger size. I photographed this white bengal tiger enjoying a dip in it's pool at Zoo Miami (Metrozoo at the time). There are no longer white tigers at Zoo Miami.
