Realised heritabilities of directly selected traits. Selection intensity is the cumulative intensity over the three generations, in units of phenotypic standard deviation. The response to selection is the divergence in the selection trait from the control line means, in control phenotypic standard deviations. Means and standard errors (SE) are included for the responses to selection and realized heritabilities. Selection intensities and responses in the up direction will have a positive sign, in the down direction a negative sign.
