@otammisalo @SashaGusevPosts Heritability in the classical twin model can go up on 2 ways: either DZ twins get less correlated over time, or MZ twins get more correlated over time. Both seem to be happening . An explanation for both of them is phenotype-&
@Pinkerite1 @ent3c @AdamRutherford @pzmyers While he is probably technically correct in the sense that heritability increases with age to around .8 as @ent3c, this quite plausibly occurs due to gene-environment covariance rather than direct genetic effects
