A broad-sense heritability of 0.8 means that genetic differences among individuals account for much of the phenotypic variation for that trait. This indicates that the trait is highly heritable and that genes play a significant role in shaping the trait. However, it does not necessarily mean that environmental influences are negligible, as they may still play some role in phenotypic variation.
