After the complete sequence of the dog genome was determined in 2005, geneticists proposed that it would be useful for finding the locations of genes associated with various inheritable traits. Domestication and breeding have made the genetic structure of the dog ideal for this application: dogs of the same breed have long stretches of identical gene sequences, making it easy to spot the few differences that can underlie inheritable traits.
