Empathy gene?

Thoughtful discussion of latest on empathy research at Ed Yong's blog at Discover:
Consider the OXTR gene. It creates a docking station for a hormone called oxytocin, which has far-ranging effects on our social behaviour. People carry either the A or G versions of OXTR, depending on the “letter” that appears at a particular spot along its length. People with two G-copies tend to be more empathic, sociable and sensitive than those with at least one A-copy. These differences are small, but according to a new study from Aleksandr Kogan at the University of Toronto, strangers can pick up on them after watching people for just a few minutes.
