No, in fact it means exactly that. This word has a technical meaning.

  Should get a different word then, since you can't get rid of confounders like prenatal diet and environment that aren't genetic but can cause you to be the same as your parents.

    In fact, you can. See, for example ACE model, which explicitly attempts to separate generic causation from shared environment and from non-shared environment. This can be done using twin studies, by comparing correlations between monozygotic vs dizygotic twins on various variables of interest, see Falconer’s formula for example. This research is not new, it has been done for many decades now. The word “heritability” has a well established technical meaning.
