Which biological gene is identified as responsible for the white coat pattern in tigers?
Answer
SLC45A2
The distinctive white coloration is genetically traceable to a specific gene designated as *SLC45A2*. This gene is responsible for controlling the specific pigment pathways that result in the creamy coat appearance while allowing the dark stripes to remain visible. It is important to note that this is the specific genetic marker identified for this particular coat variation, distinguishing it from other potential pigmentation changes found in different animal populations. The inheritance pattern of this specific gene is key to understanding why both parents must carry the recessive version for a white cub to be born.
