You don't need to be a scientist, all you need is to be well read. Articles on genetics are pretty easy to find in periodicals like Scientific American, Journal of the Americam Medical Association, Nature, even Wired. The PBS series NOVA has done multiple shows on it.
This is not subjective, it is quantifiable and repeatable. Its not theory, its measured and observed.
An I'd just like to say that I AM a scientist. I hold an Honours degree in Biology and a Masters in Biomedical research. If missmonstermuscles wants to argue with me on science, well, better bring your best ammo.
