Definition
Heritability is a statistic relating the phenotypic variation among individuals of a given population, observed at a specific time in a specific environment, to the genetic differences among individuals in that population. The term originated in its modern technical sense in 1936.

Broad-sense heritability
Jay Laurence Lush distinguished "broad heritability" from "narrow heritability" in his early writings on heritability.
