Group 1 - A Bengal white tiger named "Xiao Nao" has gained significant popularity on the internet due to its beauty, attracting visitors to the Qingdao Zoo [1][3] - The tiger, which is 10 years old and considered a "star" of the zoo, has been admired for its striking appearance, including features like white fur and large eyes [7][3] - The tiger's lineage includes parents with excellent traits, contributing to its appealing genetics, and it has a total of five siblings, with some also receiving attention from the public [9][11] Group 2 - The white tiger is not a separate subspecies but a genetic mutation of the Bengal tiger, with only about 200 individuals remaining globally, all of which are bred in captivity [12][14] - The white fur results from a double recessive gene mutation affecting pigment production, making the tiger's fur white with black stripes, a mutation that occurs naturally at a very low probability of about 1 in 10,000 [12][14] - In the wild, the white fur reduces the tiger's ability to camouflage, leading to their near extinction in natural habitats, with current populations relying on artificial breeding in protected environments [14]
