👉 Melanistic is a term used in the field of genetics that refers to a specific type of mutation in which the color of an organism's skin changes when exposed to UV light. This process can be caused by mutations in genes that control pigmentation, and it can also result from exposure to harmful UV rays during the day or at night. Melanin is the pigment that gives the skin its characteristic shade, but mutations in melanin genes can cause a range of other effects as well.
