| We do not know the relative contributions of heritability and environmental influence on abusive behaviours. |
| If you look at the heritability of depression, it's a similar kind of story. |

| Perhaps this heritability was limited to those cases in which the heiress transmitted the de facto headship of her house. |
| Clearly, contemporary views of heritability are populist market eugenics in a new form. |
| It is striking that studies of twins regularly come up with higher levels of heritability than do other sorts of studies. |
