Fascinating. But there's a level of scientific understanding to your comment that I just don't understand. Do you have any recommendations for learning resources to better grasp what you're talking about?
It just means that multiple genes contribute to the outcome, so it's not a binary flip of THC or CBD depending on a single gene - if it were like that, then two parents who had the CBD gene would almost certainly produce CBD kids. Polygene means that it's a more complex interaction, and you can't assume that two CBD parents will result in a CBD child.
