Another genetic characteristic makes the stripes of the tiger very pale; white tigers of this type are called snow-white or "pure white". White tigers, Siamese cats, and Himalayan rabbits have enzymes in their fur which react to temperature, causing them to grow darker in the cold. In the Bristol Zoo, a white tiger named Mohini was whiter than ...

The Siberian tiger or Amur tiger is a population of the tiger subspecies Panthera tigris tigris native to Northeast China, the Russian Far East, [1] and possibly North Korea.

The snow-white tiger is a morph with extremely faint stripes and a pale sepia-brown ringed tail. White and golden morphs are the result of an autosomal recessive trait with a white locus and a wideband locus, respectively. The snow-white variation is caused by polygenes with both white and wideband loci. [62]
The study reveals that the snow leopard and the tiger are sister species, while the lion, leopard, and jaguar are more closely related to each other. The tiger and snow leopard diverged from the ancestral big cats approximately 3.9 Ma. The tiger then evolved into a unique species towards the end of the Pliocene epoch, approximately 3.2 Ma. The ...
A Panthera hybrid is a crossbreed between individuals of any of the five species of the genus Panthera: the tiger, lion, jaguar, leopard, and snow leopard.Most hybrids would not be perpetuated in the wild as the territories of the parental species do not overlap and the males are usually infertile.
The Caspian tiger used to occur along the upper reaches of Hari-Rud near Herat to the jungles in the lower reaches of the river until the early 1970s. [13] Uncertain is the historical presence of the Asiatic lion in the country, as locality records are not known. [11] It is thought to have been present in southwestern and southern Afghanistan. [14]
