Nova: Ghost in Your Genes

PBS This 60-minute report on the field of epigenetics suggests that factors besides genes could affect inherited traits. It might be that, say, nutrition and stress change the way genes act, by triggering chemical switches in them without altering their overall makeup, and those changes could be passed along to kids and grandkids. Babies conceived by [the immoral process of] in vitro fertilization often have Beckwith-Wiedemann Syndrome; an IVF-caused effect could be the reason. A re-air.

WEDNESDAY, 8 p.m.
