Every year at Crufts, dog owners line up to buy DNA kits to uncover the mysteries waiting in their pups genomes. However, new discoveries could end up changing our favourite breeds forever.
Visitors to the DNA-testing stands are presented with leaflets denoting the dizzying number of things that genetic tests can tell owners about their dogs. There are the obvious ones – a dog’s precise breed, and those of its ancestors as well its likelihood of developing a range of health conditions. But there are other details waiting to be uncovered within a dog’s genome: whether it will grow a moustache and bushy eyebrows, for example, or the identity of its long-lost uncle.
