Bengal tigers are unlike pure white tigers which have absolutely no stripes overs their body and are pure white in colour but Bengal have strips which are used to camouflage in tall grasses when hunting for prey. Their stripes are like fingerprints which means none are the same and can identify what kind of tiger they are.

For the white fur the White Bengal tiger is born through inbreeding and when both parents carry the gene for the white fur. Inbreeding is when tigers mate father to daughter, brother to sister, mother to son and so forth. This is because the white color is the result of a double recessive gene so the white color can only be produced by inbreeding tigers that carry the recessive gene for the white color to get to the cub. But that would only result it being 50 - 50 being white. It is said that the chance for it to happen in the wild is 1 in 10000 births. You can let two tigers of the same white gene mate and the cub would have a 100% chance of being white. Still most of the time that inbreeding happens the cub will normally be born with some sort of health problems.
