Orange Cat Mystery
- Orange coloration in many animals, including humans, is well-understood.
- However, the genetic mechanism behind orange fur in cats remained a mystery until recently.
Genetic Breakthrough
- Two new studies reveal the genetic basis for orange fur in cats.
- These studies identify specific genes and loci responsible for melanin production and color variation.
Unique Cat Genetics
- In cats, the control of eumelanin and pheomelanin production isn't determined by the MC1R protein like in other mammals.
- Instead, a locus called "orange" plays a crucial role in cat pigmentation.
