Here is the dog genome
He has been with us for thousands of years; here is finally the whole sequence of the dog's DNA.

Dogs have been differentiated from humans in dozens of breeds, all of which have a very similar genome.

After the man's genome, here's that of his best friend. In the number 301 of the American journal Science is in fact described the first draft of the entire genetic heritage of the dog. The DNA comes from a poodle named Shadow (Shadow) whose master is Craig Venter, the researcher whose privately funded research projects fought for a long time to take precedence over the Human Genome Project, of governmental origin. So far, about 2 million canine DNA fragments have been sequenced, which corresponds to 80 percent of its genetic heritage. Although the project is far ahead, for now researchers have only a rather rough sketch of how the dog genome is composed. However, they were able to determine that 18, 473 canine genes have a human equivalent, more than 18, 311 of the mouse. According to the researchers, some of these genes correspond to those that in humans determine certain types of cancer, epilepsy, narcolepsy and other human diseases.
There is also Tasha. At the same time, even a US-funded company is trying to sequence the genome of a boxer, named Tasha, and publish the results at the end of the year or early next year. A boxer was chosen because the genetic variability of this breed of dog is very low.
The sequencing of the canine genome should allow to know in depth the structure of the various breeds, as for example because the collie is a good shepherd, or the hounds of Sant'Uberto are excellent "sniffers". Obviously the aim is also to reveal where the health problems of dogs hide, and to develop new breeds based on known characteristics and the presence of particular genes.
