Knowing a trait's heritability coefficient can help scientists understand the extent to which genetics play a role in the development of that trait. This information can be used to design studies that investigate the underlying genetic mechanisms that contribute to the trait. It can also be used to predict the likelihood of the trait being passed down from one generation to the next. Additionally, understanding the heritability of a trait can help scientists develop treatments or interventions that target the genetic factors that contribute to the trait.
