Figure 2.
Copy number variants (CNVs) in the four main classes of dog breeds. DNA from nine pedigreed dogs was cohybridized with a reference pedigreed Boxer. The first panel shows a change in all dogs but the Boxer. As the reference is another Boxer, we presume the CNV is a gain in Boxers. The second panel has a gain CNV specific to the two Akitas. The next two show CNVs shared by herding and hunting, and herding and mastif breeds. The last shows a CNV present in a single herding dog, a Collie.
