    Genetic effects across the genome may exhibit context dependence
    - European vs. East Asian genetic correlation is less than 1 across a wide range of traits.
    - Hinting at polygenic GxE

    GxE can arise through different scenarios
    - Imperfect genetic correlation
    - Varying genetic variance
    - Proportional amplification

    A New Test for Trait Mean and Variance Detects Unreported Loci for Blood Pressure Variation
    Todd L. Edwards

    If there is a GxE, then variance of Y differs by genotype.

    If we don't know E, we can model both the mean & variance as function of the main predictor.

    Known a long time - e.g. Waddington (1942) Canalization of development and the inheritance of acquired characters.
