Heritability estimates for temperament in beef and dairy cattle tend to be moderate to high, indicating that selection for improved temperament would be effective. As a comparison with other traits, reproductive traits tend to be lowly heritable and carcass traits are more highly heritable
This is taken from an American Angus Association published paper:

Is there such a thing as a happy black angus?
