After 60 years of searching, geneticists have finally identified the gene behind the marmalade coloration in domestic cats. Two independent teams of researchers found any fiery-hued fuzz on our beloved clawed floofs is likely the result of a missing segment of DNA in a non-protein-coding part of the cat's genome. "It's been a genetic mystery, a conundrum," Stanford University geneticist Greg Barsh told Sara Reardon at Science. Barsh and his colleagues discovered cat skin cells from which orange fur sprouts express 13 times as much RNA from a gene called Arhgap36, compared with skin cells from cats with no orange...
