Explanation:

As per the scientists, genetic mutation among tigers changes an amino acid responsible for the normal colour being formed, resulting in “natural polymorphism”. According to the scientists, white tigers lack pheomelanin, which is responsible for the red-yellow hue in the skin coat.
In India, white tigers are predominantly found in Rewa, Madhya Pradesh.
White tigers in India are nothing but a pigmentation variant of the Bengal tiger. They have been reported in the wild from time to time in the Indian states of Assam, West Bengal, Bihar. These tigers have white fur because of the lack of the pigment pheomelanin, which is found in Bengal tigers with orange colour fur.
