Scientists have been studying domesticated silver foxes to determine which genes might be responsible. A gene known as WBSCR17 has been identified as a probable gene for domestication, as dogs and wolves also differ in the expression of this gene. Interestingly, there is a human genetic condition called William's Syndrome, which results from a.

Until recently, however, the tools for conducting molecular genetic investigations in this species were very limited. In this review, the history of development of this resource and the tools to exploit.

Like many breakthroughs in science, Dmitri Belyaev's silver fox domestication experiment began with a thunderbolt: one simple, powerful, new idea. Born of a parish priest in early 20th century Russia, the geneticist proposed that all domestic animals were tamed through a generations-long process in which our distant ancestors repeatedly chose the calmest animals — those that were.

The rigorous selection of the silver fox solely for tameability brought about correlated changes in certain features of behavior, physiology and morphology. Thus, the rise of the dog-like ability of foxes to "read" human social cues, for example, gestures and glances, was a noteworthy change in their behavior.
