Transgenerational epigenetic inheritance is the transmission of information from one generation of an organism to the next that affects the traits of offspring without alteration of the primary structure of DNA —in other words, epigenetically.
Epigenetics is the study of heritable phenotype changes that do not involve alterations in the DNA sequence. The Greek prefix epi- in epigenetics implies features that are “on top of” or “in addition to” the traditional genetic basis for inheritance.
Dr. Michael Skinner lays down how environmental exposures can impact epigenetics and generations to come. This short take was shot during a break at Keystone Symposia’s meeting on Environmental Epigenomics and Disease Susceptibility held in March 2011 in Asheville, North Carolina. this video speaks of transgenerational epigenetic inheritance and epigenetic modification.
