Somewhere around 24,000 genes and their respective locations have been identified on a dog's 78 chromosomes. Even cooler: the many ways we've put this rich information to good use. Breed Identification This type of genetic testing has been all over the news in recent years. It beats me why people are so keen to know which breeds are responsible for their dogs' inner beauty, but if it helps someone better understand her pet, I'm all for it.

Where Do Dogs Come From? DNA Study Says It's the Middle East

Locked deep in the DNA of man's best friend are secrets and clues that have teased scientists for years, ever since the discovery that dogs evolved from wolves long, long ago. But when, where and how did it happen? It's an ancient puzzle that experts are still trying to piece together, with intriguing results. Just last week, an international team of researchers announced they had finally figured out where in the world dogs first originated: the Middle East, though they can't pinpoint a more specific location. "Dogs seem to share more genetic similarity with Middle Eastern gray wolves than with any other wolf population worldwide," one of the study's lead authors, Robert Wayne, professor of...

craigallyn, Flickr From chihuahuas to bulldogs to giant Great Danes, dogs come in a dizzying assortment of shapes and sizes. That makes them all too perfect for scientists who study how genes work. In a recent essay in the scientific journal PLoS Biology, researchers from the National Human Genome Institute wrote about the major advances in understanding how dog genes translate to the rainbow of traits that make up the modern pooch. More than 300 dog breeds are known around the world, including the 170 official American Kennel Club breeds. For hundreds of years, dog breeders have accidentally been creating a perfect model for studying genetics. Now science is reaping the benefits. Not...
