Do Black Mice Exist? Rare Color Variants
Dark fur in mice results from elevated eumelanin production, a process governed by several well‑characterized genes. The melanocortin‑1 receptor (MC1R) encodes a protein that, when activated, shifts melanin synthesis toward eumelanin. Loss‑of‑function mutations in MC1R reduce this signaling, allowing the default production of pheomelanin and yielding lighter coat colors.. Date latest changes: 2025-10-06 13:26
