The highest estimates in narrow-sense heritability
These values set a limit to the narrow-sense heritability
value, which considers only additive genetic variance.
Similarly, there is a wide range of variation for narrow-sense heritability
and predicted gain with selection estimates for iron and zinc concentrations in Middle American and Andean common bean seeds (Cichy, Forster, Grafton, & Hosfield, 2005; Jost et al.
It indicates that the narrow-sense heritability
cannot be achieved satisfactorily in complex diseases and traits with a complex inheritance such as human height (Eichler et al.
We also used a "family-based" version of this method to estimate the full narrow-sense heritability
, which reflects the additive contributions of all variants, including unmeasured rare variants (Yang et al.
The narrow-sense heritability
is the ratio of additive genetic variance to the total phenotypic variance.
Considering the significance of the variance of genotypes, Hayman method  was used to calculate the trait controlling genetic parameters including additive effect, dominance effect, average dominance degree, number of trait controlling genes, the ratio of the genes having positive and negative effects in parents, broad-sense and narrow-sense heritability
, and graphic analysis.
sigma]]) is equal to the product of the variance-standardized selection gradient and the trait's narrow-sense heritability
is defined as the proportion of resistance that is controlled by additive gene effects (Poehlman and Sleper, 1995).
Alternatively, resemblance between biological parents and their offspring given up for adoption may be used to estimate narrow-sense heritability
Each regression coefficient and its standard error could be related to narrow-sense heritability
(the ratio of additive genetic variance to phenotypic variance) after doubling because measurements were only made on one parent.
In our study, broad-sense and narrow-sense heritability
