Ghost in Your Genes Viewing Guide
... BACKGROUND: "Ghost in Your Genes" focuses on epigenetic "switches" that turn genes "on" or "off." But not all switches are epigenetic; some are genetic. That is, other genes within the chromosome turn genes on or off. In an animal's embryonic stage, these gene switches play a main role in laying out ...
