No, not all variation is additive, but things like twin studies and GCTAs let you estimate the additive part of the heritability. (I can't tell whether you're completely ignorant of this topic & wildly overestimating the cogency of your comments, or just being a Socratic dick, so it would be helpful if you could clarify.)
