In addition to adoption studies, a lot of analysis of heredity can be (and has been) done in twin studies, comparing and contrasting the variation between twins and "ordinary" siblings; and fraternal vs identical twins.
You're right in that there is a limited number of studies, in part because you're looking at small populations and you don't get that many new adoption or twin cases each year. However, in that regard it's worth looking at equivalent studies worldwide who each have tested their local adopted or twin children; as far as I understand, these studies in different countries generally confirm the same or similar results, but I have not personally gone in detail to verify that.
