The paper introduces RAVEL, a framework to estimate genetic nurture effects by distinguishing direct and non-transmitted genetic associations in parent-offspring trios, finding assortative mating explains most apparent parental genetic influence on child cognition.

The paper develops a framework to estimate genetic and social homogamy using family data and finds that indirect assortative mating better explains educational attainment similarities than direct assortment.

The paper shows genetic similarity between relatives can indicate assortative mating, finding evidence in nine traits and increased genetic variance in offspring for six of them.
