S Matrix, Genetic Correlations, and Twin Models

Is genetic correlation (off diagnonal values in the S matrix) more similar to bh2 (bivariate heritability) or rg (genetic correlations) in the bivariate twin models?

Replying to “Is genetic correlation (off diagnonal values in t…”:

Here, similar to bh2

If we standardise the S matrix, that will be similar to the rg from bivar twin models
