The tiger (Panthera tigris) is most recognized for its dark stripes against an orange background. Less well known are three other pelage color variants: white, golden and stripeless snow white. Dear Editor, The tiger (Panthera tigris) is most recognized for its dark stripes against an orange background.
Less well known are three other pelage color variants: white, gold-en and stripeless snow white (Figure 1A). The white tiger is a polymorphism that was first seen among wild Bengal tigers (P. t.
tigris) in India, with white fur and se-pia brown stripes [1]. The golden tiger, also. The research investigates the genetic underpinnings of pelage color variations in tigers, focusing on the white, golden, and snow white morphs alongside the typical orange coloration.
It identifies the genetic loci responsible for these traits, particularly highlighting the autosomal recessive traits linked to the white and golden tigers, and the polygenic factors involved in the snow white.

The Genetics of Tiger Color The most common tiger coloration results from the normal expression of genes controlling melanin production. Melanin is the pigment responsible for both the orange/yellow base coat and the dark stripes. When genes responsible for melanin production are affected by recessive mutations, we see color variations emerge.
The white tiger, for example, carries a recessive. While the baseline coat color and pattern are genetically determined, rare variations arise from genetic mutations -spontaneous changes in a tiger's DNA. These mutations can alter the production or distribution of pigments like eumelanin (black/brown) and pheomelanin (red/yellow), leading to unexpected colors.
This uncanny widening of a tiger's black stripes, a rare genetic mutation known as pseudo-melanism, is shared among roughly half the 30 or so tigers that roam the Similipal reserve.

White tigers, black panthers, and other animals with unique color mutations are rare in the wild. Additionally, the few born with color mutations may struggle to survive. For example, a white tiger would not be as well.
