STANFORD, Calif., Nov. 6 U.S. researchers have found a gene
previously believed to play a role in fighting infection
actually determines coat color in dogs.
Led by genetics Professor Greg Barsh of the Stanford
University School of Medicine, the scientists confirmed the
long-held suspicion that coat color in dogs is determined
by a different genetic mechanism than the one responsible
for coat color in other mammals.
Barsh and his team swabbed the inner cheeks of hundreds of
dogs and analyzed the DNA in the resulting samples. They
found the gene controlling coat color in dogs makes a
protein that had been believed to fight infections, but
which actually controls the type of melanin the body
produces as well as the amount of cortisol -- a chemical
important for the adaptation to stress and the regulation
One version of the gene produces yellow fur while another
version produces black fur. The research team found that
all coat colors in dogs are modifications of black and
Barsh said the team's work might have important
implications for the development of personalized medicine
and individualized treatments based on genetic factors.
The research appears in the journal Science.
|Cool post, never really thought about it, but ya I guess all colors on dogs are some kind of yellow and black (this does not take into account some pink and blue poodles I saw)|
|Don't think there is a genetic component to food coloring|
|it was one of the funniest/meanest things I had ever seen, poor dogs
