Producing the red-yellow pigment (pheomelanin) causes less oxidative stress, and is more simple. This means it is easier for ...

In cats, eumelanin or pheomelanin production is not controlled by the MC1R receptor. Instead, it is in the hands of a locus (whose gene was, until now, unknown) called "orange".

Two types of melanin are commonly found in human hair: eumelanin and pheomelanin. While eumelanin is responsible for the black and brown colors of human skin and hair, pheomelanin gives hair a red ...

Producing the red-yellow pigment (pheomelanin) causes less oxidative stress, and is more simple. This means it is easier for stem cells to continue to produce pheomelanin, even as they reduce their ...

With particular variants of the MC1R gene, melanocytes produce mostly pheomelanin, leading to red hair and fair skin. Get the Popular Science daily newsletter💡 Breakthroughs, discoveries, and ...

Scientists have finally solved the greatest feline mystery of our time: Why is it, exactly, that some cats are orange? Two separate research teams have detailed the answer in two studies published ...

Any animal’s eye color is determined by its levels of two melanin pigments: eumelanin, which makes brown-black, and pheomelanin, which makes red-yellow.

In cats, eumelanin or pheomelanin production is not controlled by the MC1R receptor. Instead, it is in the hands of a locus (whose gene was, until now, unknown) called “orange”.
