Stanford's Youtube channel has a series of lectures for Robert Sapolsky's class on Human Behavioral Biology, and he spends a good amount of time on genetics there. The view he presents there is that there is no such thing as a gene FOR something, because the effect of a gene is a function of the environment in which it is expressed. For example, it's incorrect to think in terms of a gene for depression, but it is more reasonable to think of a gene that will make you vulnerable to depression if you are exposed to strong stressors during childhood. I recommend watching the entire playlist, but I've linked to the punchline at the end of Behavioral Genetics II. I've linked to him discussing the heritability of plant IQ, followed by the heritability of depression example I alluded to earlier. https://youtu.be/RG5fN6KrDJE?t=3200 https://youtu.be/RG5fN6KrDJE?t=3200 Again, I recommend watching the entire lecture if you have an hour and a half, both lectures if you have 3 hours, or all the lectures if you have, like, 40 hours.
