Some of the traits that the study reported as having more than a 0.50 heritability ratio include leadership, obedience to authority, a sense of well-being, alienation, resistance to stress, and fearfulness. The implication is that some aspects …

WitrynaGiven its definition as a ratio of variance components, the value of heritability always lies between 0 and 1. For instance, for height in humans, narrow-sense heritability is approximately 0.8 ... WitrynaAn important concept in quantitative genetics is the narrow sense heritability (h 2), which is defined as the ratio of additive genetic variance to the total phenotypic variance (h 2 = σ A 2 σ P 2) (Falconer and Mackay, 1996; Lynch and Walsh, 1998). Put simply, the narrow sense heritability of a quantitative trait is the reliability of an ...
