I've deleted this considering there is no known controversy about DNA being the genetic material and considering there were no responses to this post giving any reason to keep it. I can see how it might be handy to have mention of other mechanisms of inheritance such as epigenetics somewhere else in this article but I'll leave that for other people if they so choose. 2403:7900:ADE1:A1DE:250:56FF:FEA6:3B1F
