- By the presence of melanocytes, carotene,
- Oxygenated haemoglobin, and
- Blood flow.
What type of variable is skin colour?
"Skin colour is a classic variable characteristic in humans, and it's thought to be adaptive," Tishkoff said. "Analysis of the genetic root of variation in skin colour sheds light on how adaptive traits evolve, including those that play a role in disease risk."
Thus, the presence of melanocytes, carotene, oxygenated haemoglobin, and blood flow.
