Stanford Medicine researchers discover mechanisms of sex-linked genetic mutation giving rise to ginger felines.

Researchers identified an unusual genetic mutation in orange domestic cats that has not been found in any other animal, according to a new study.

In cats only, a small deletion of information on the X chromosome activates Arhgap36 in pigment cells where it is normally not active, triggering orange fur. Males have XY sex chromosomes and ...

Everything you need to know about genetics, you can learn from your cat,” said Leslie Lyons, a veterinary scientist at the ...

But 48 were also found in non-orange cats, which left three likely candidates for the elusive mutation. One was a small, 5,076-base pair deletion that removed about 0.005% of the X chromosome in a ...

there’s a fairly small chance it will be expressed by every cell and present as an even (or even semi-even) orange coat. To be orange, a female cat must have the orange gene on both X ...
