Summary:
- Cats can have different fur colors, including orange or "ginger" fur. This is determined by a gene called the MC1R gene.
- The MC1R gene controls the production of a pigment called pheomelanin, which gives the orange/ginger color. Certain variations in the MC1R gene can lead to more or less pheomelanin being produced, resulting in different shades of orange fur.
- Researchers have discovered that the orange/ginger fur color in cats is caused by a specific mutation in the MC1R gene. This mutation allows for more pheomelanin to be produced, leading to the distinctive orange coloration.
