A group of scientists from Princeton, Oregon State University and other institutions combined behavioral and genetic studies of 16 dogs and eight captive, socialized wolves to pin down changes in two genes on a region of one chromosome that were associated with hyperfriendliness in dogs. The two genes, GTF2I and GTF2IRD1, are also associated with Williams-Beuren syndrome in humans, said Bridgett M. vonHoldt, an evolutionary biologist at Princeton University and an author of the study.
