WitrynaHeritability estimates are single numbers ranging from 0.0 to 1.0. An estimate close to 0.0 indicates very little contribution from genetics, while a heritability estimate close to 1.0 suggests that nearly all the variability in risk can be attributed to genetics, with little contribution from environmental factors. Witryna29 mar 2012 · Author Summary The narrow-sense heritability of a trait such as body-mass index is a measure of the variability of the trait between people that is accounted for by their additive genetic differences.
