the proportion of observed variation in a particular trait (as height) that can be attributed to inherited genetic factors in contrast to environmental ones
In the narrow sense, heritability is defined as the proportion of the total phenotypic variance in a trait that is due to the additive effects of genes, as opposed to dominance or environmental effects In the broad sense, heritability is the proportion of the total phenotypic variance of a trait that is due to all genetic effects, including additive and dominance effects Source : PhRMA Genomics
