You can’t judge a book by its cover. But you can judge a dog by its coat. You can even read right through to its genes2. Because a study in the August 27th online issue of Science shows that just three key genes govern the length and texture3 of dog fur.
Domestic dogs come in a stunning4 variety of shapes and sizes, and different breeds wear different coats. They can have short hair or long hair, or fur that’s straight, wavy5, curly, wiry or smooth. To find the genes responsible for this furry6 rainbow, scientists scanned the DNA7 of a thousand individual dogs from 80 different breeds. And they found that every coat’s appearance boils down to three simple traits: length, curl and texture. And that each of these traits is controlled by just one gene1.
So, a long-haired Golden retriever has one variant8 of a gene called FGF5, whereas a short-haired lab has another. By mixing and matching variants9 of these three genes, you get everything from a curly-haired poodle to a wire-haired Scottie with bushy eyebrows10 and a droopy moustache.
Which is probably more than you’ll ever need to know about the hair of the dog that bit you.
