How dogs can help unravel genetic diseases in people (via

Unlike people and mutts, purebred dogs have been bred from a small number of ancestors, making them the perfect subjects to teach us about the genetic links that lead to many diseases in humans, according to researcher Elaine Ostrander of the National Human Genome Research Institute.  The combination of intense breeding, known pedigrees and the sequencing of dog genomes, allows researchers to more easily trace the origins of deadly diseases in canines.  Once genes associated with a particular disease are identified, scientists can then  look for some for similar genes in humans.  The research is highlighted in a recent article published in the New England Journal of Medicine.
