Nice job explaining epigenetics. I worked in a Nutrition and Genetics lab for several years and we worked with mice. We always looked at the methylation levels on liver and in sperm via pyrosequencing methods. Our lab was curious about cross-generational epigenetic inheritance. I had a meager Associates degree in Biotech and it took a good bit of studying before I understood the chemistry and science behind methylation and epigenetic inheritance. The fact I could read and understand your article means I actually retained some useful knowledge. Thanks for sharing!
