The way this is described makes me think it's kind of like a talent for a certain sport. The genetic influence is, say, that you were born 6'7" and are as broad as a barn. That chance manifestation of those genes gives you a natural advantage or skill at football, but if you were born in, say, a country where football isn't a thing, you're not going to develop that ability. Or if your family thinks sports are for rubes, you're going to disdain and not explore that expression of your physicality.

That metaphor isn't entirely sound, I think, but you can get the point.
