Wei-Chao Huang works in Gregg's lab at the University of Utah. The team has   been hard at work the last four years to find proof against a principle notion in genetics -- that gene copies from a mother and father are treated the same. Their research has found that some genes in the brain, as well as other regions in the body, preferentially activate one copy over the other. Wednesday, March 1, 2017.
