Question

What can fish color tell us about human pigmentation? skin color is often one of the first traits people notice in each other. studies in zebra fish uncovered a mutation that altered a transport protein and resulted in light-colored fish. this discovery led to the finding that the same gene in humans has a strong influence on skin pigmentation in many populations?

Answer 1

The skin color of fish is used to demystify human skin pigmentation. As revealed by studies, a fish skin color is influenced by both genetics and the environment. For example, the skin pigmentation of fish exposed to a more saline environment and fed saltier food is different compared to fish exposed to a lower concentration of salt. Based on years of studying fish skin color, it can be deduced that the variety of human skin pigment is also influenced by genetics plus the environment.
